1 Bid Data Sheet ITB Clauses 21 and 24.1, Page 50

The Deadline for Submission Of Bids is 15 July 2019, 12:00PM

the date and time of Bid Opening is on 15 July 2019, 1:30PM
We request to extend the Bid Submission and Opening from 15 July 2019 to 15 August 2019 so that we can thoroughly prepare the documentation relative thereto, among which is the JVA documentation The Bid Opening has been scheduled on October 1, 2019
2 Schedule of Requirements Number2,Page80

Hauling, delivery, supply and installation of towers and facilities materials

Within one hundred twenty (120) days after the approval of detailed design, tests, plan, etc
We request to extend the delivery lead time of towers from 120 days to 18 months upon approval due to the fabrication and hauling process of towers Denied.
3 Bid Data Sheet ITB Clause 12, Page46

the Bidder must hold a minimum of 20 years PCAB license in General Engineering on or before the date of the bid opening, with an AAA Category.
We request to waive the partially the requirement of the holding of a minimum of 20 years PCAB license in General Engineering on or before the date of the Bid opening, with an AAA Category from the bidder, and in lieu thereof;

1. We request to allow 3 years of holding of such a license should be considered as sufficient for both General engineering and Communication Facilities

2. We request to allow A or B category for General Engineering and Communication Facilities should be considered as well

3.Such PCAB in General Engineering license BE REQUIRED FROM THE FABRICATOR partner of the bidder and NOT from the bidder (not from the Bidder itself) since this is primarily a bid for Microwave Radio. Most companies who will join are either supplier of equipment BUT NOT a tower fabricator at the same. SO it is almost impossible to be both a supplier of both microwave radio and fabricator of towers at the same time.

The principal equipment to be delivered under this Project is MW Radio, only with Antenna Towers, that is 3- legged/Monopole_ self-supporting Tower or 4-legged self- supporting tower, which requirement as to towers can be put up by a PCAB Licensee not necessarily under AAA Category. Hence, the AAA PCAB License requirement is too high of a category. In relation thereto, too long possession of such a license for a period of at least 20 years appears to be restrictive.

The waiver will allow more participants and make the bidding more competitive
Change to: The bidder must hold a PCAB License with Category AAA in General Engineering for a minimum of two (2) years on or before the date of the bid opening. For joint venture, at least one of the JV should comply to this requirement. .  
4 Bid Data Sheet ITB Clause 5.4, Page

11 Schedule of requirement item 7, page81

Two (2) years Operation and maintenance support (inclusive of two (2)- year warranty parts and labor, free of charge)
Please consider the operation and maintenance support of 8 hours x 5 days, Monday to Friday. Denied.
12 Technical Specifications Item 1.1.5, Page 84

Shall support the following modulations schemes without any hardware change, or additional boards: QPSK, 16QAM, 32QAM, 64QAM, 128QAM, 256QAM, 512QAM, 1024QAM up to 4096QAM whichever is applicable per site
Since this is a bid that includes DETAILED DESIGN, kindly allow modulation scheme up to 2048QAM. 4096QAM is not usually used for backbone or long haul transmission and the capacity increase of this modulation is negligible if we compare it to 2048QAM. Denied.  The modulation scheme of 4096QAM may not be required in the hops in this project, however, it still have to be at least supported, in case we need higher capacity or reallocation with higher capacity requirement.  There should be about 8~10% capacity increase per RF which is not negligible and further mutiplying that increased capacity with the no. of MODEMS or Channels your MW Radio System can accommodate, which in this RFP, we prefer up to 12 MODEMS or 12-Way, would definitely provide a better scalability for the MW Radio System if you can comply.
13 Technical Specifications 1.1.6, Page84

Frequency: the equipment shall support all licensed bands L6 to 42 GHz.
Since this is a bid that includes DETAILED DESIGN, kindly allow “the equipment shall support ANY of the licensed bands between l6 to 42 GHz as what may be required depending on the bidders design”.

high frequencies are not usually used for backbone or long haul transmission design.
Denied.  This RFP does not require the bidder to design all hops using all frequency bands. The bidder is given the liberty to propose its own recommended frequency based on the link budget design requirement using the KPIs provided in the RFP (Avail=99.99%, 35dBm).  However, the bidder is still compelled to comply that it can support L6GHz uo to 42GHz for flexibility.
14 Technical Specification Item 1.1.6,Page84

ODU that is tunable to the whole frequency (sub-band free.) Vendors shall state what kind of free tunable ODU can be provided. Self Frequency scan is required.
Since this is a bid that includes DETAILED DESIGN, the mentioned reference statements are not applicable  for long haul transmissions.

sub-band free radios are usually used for access radios and not for long haul radios which filters are needed.

if DICT needs to have removable diplexers on the ODU, the IP66 compliance (waterproof and dustproof) will be affected.

self frequency scanning is used in PTP UNlicensed radios. this is not needed with licensed radios since the frequency is dedicated to one (1) user only.
Please note that preferred equipment to be supplied in this proposal is Outdoor/Split-Type System.  If you are proposing a Long Haul Transmission Radio System which uses indoor filters and connected to antenna via waveguide, then this is not this RFP’s preferred radio type to be supplied.  However, if you are referring to the “outdoor” filters which you intend to supply which probably includes the duplexer units, these all have to be for outdoor use.
ODUs to be used should be sub-band free, provide such information in your proposal to identify which frequency bands are supported.
ODU’s IP66 compliance is non-negotiable.  Removable items, such as diplexers, are not preferred.  ODUs should have wide-band filters.
Self-freqeuncy scanning can also be defined as being able to check for the suitable point frequency to be used using the installed ODUs and having the opposite station in mute mode for transmitting, then checking at local station if interferences are observed.
15 Technical Specifications Item 1.1.10,Page84

Receive Signal threshold Sensitivity: the radio equipment must have signal sensitivity of BER 10-6 of -60dBm or better.
Since this is a bid that includes DETAILED DESIGN, please allow the bidder to state their own Receive Signal Threshold Sensitivity. (same as the transmit power) in reference  to the equipment configuration per site.

Please not that the Receive Signal Threshold Sensitivity (same as the transmit Power) depends on the modulation and frequency used which is based on the bidders design.
Denied. The Bidder is required to provide their equipment’s Receive Signal Threshold.  It is understood that Receive Signal Threshold shall be based on modulation, bandwidth and frequency band which shall be in accordance to bidder’s link budget calculation, however, it should still be -60dBm or better at BER10E-6.  Better Transmit Power and Receive Signal Threshold translates to better system gain, and DICT will also evaluate proposed radio systems in this regard.

50 Link Requirements and Equipment Characteristics
 1.1.1. IP Microwave radio should either be Outdoor/Split system, must adopt modular design, the service boards can be plugged/ unplugged.
 
 In case of a Split System,
 
 1.1.1.1. IDU shall support cascading;
 1.1.1.2. IDU must have an attached cooling system.
 1.1.1.3. The distance between IDU and ODU can support at least 100 meters
 1.1.1.4. Control unit is required to be configurable to 1+1 Hot standby.
a. Does outdoor system mean full outdoor? If yes, what is the requirement for full outdoor system since the document specifies split system?
 B. Full outdoor system does not have service board, is it acceptable?
 C. Control unit required to be 1+1 Hot standby, does it mean there is no need to have the whole split mount system (IDU+ODUS) in 1+1 Hot standby?
A.  The Outdoor/Split-Type System pertains to MW Radio Systems that are Split-Type with Outdoor Unit.  MODEM Part is indoor while TX/RX (RF) Part is outdoor.
B.Full Outdoor is not preferred in this RFP.  MODEM and INTERFACE part should be easily accessed for ease in O&M.
C. The Control Unit should be redundant.  Traffic shall be protected through RTA for more than 1 RF canannels.  However, the offered system should be able to support 1+0, 2+0, 1+1 HSB/SD/FD, XPIC Configuration.  Where SD configuration shall be used for overwater propagation, when necessary, to counter fading due to reflection.
51 1.1.2. Capacity: The desired microwave IP radio should have a guaranteed link capacity of at least 200Mbps (Full Duplex) upgradeable to 2Gbps. The vendor shall propose any suitable configurations to meet the desired requirements by the DICT, all subject to review and approval of DICT. What does upgradeable to 2Gbps entails? Is it via large bandwidth/channel spacing like 112 MHz or via adding more RF Channels/carriers? The requirement of the MW Radio to be able to support upgraeability up to 2Gbps can be a combination of increased modulation, increased bandwidth and additional RF channels.
52 1.1.4. Reliability Methods: ITU-R P.530-7/8 with Fade Margin of at least 35dB (minimum). 35dB Fade Margin will entails the use of larger antenna size to cater to the short period of average path condition is there a limit to the size of the antenna? There is no limit to the size of the antenna, however, if other vendors can propose smaller size antennas it means that their radio system is more superior in terms of sytem gain and in consideration of other losses.
53 1.1.5. Modulation: The equipment shall support modulation schemes with full range of hitless and errorless Adaptive Coding Modulation (ACM). ATPC and ACM can work together at same time, increasing TX power of ATPC function should be made prior to dropping modulation mode of ACM. When the modulation is adjusted to lower level modulation scheme, the max TX power of the radio should be adjusted to the corresponding level in real time.
 
 • Shall support the following modulation schemes without any hardware change or additional boards: QPSK, 16QAM, 32QAM, 64QAM, 128QAM, 256QAM, 512 QAM, 1024QAM whichever is applicable per site.

Is 409QAM mandatory since such a high modulation can only caters to very short distance depending on the frequency band? The modulation scheme of 4096QAM may not be required in the hops in this project, however, it still have to be at least supported, in case we need higher capacity or reallocation with higher capacity requirement.
55 1.1.6. Frequency: The equipment shall support all licensed bands L6 to 42 GHz. ODU that is tunable to the whole frequency is preferred. Vendors shall state what kind of free tunable ODU can be provided. Self-frequency scan is required. Is tunable frequency refers to the whole band within the diplexer range? Is self-frequency scar can refer to build-into the licensed band microwave transmission system? All frequency pair spots have to apply to NTC and need to scan first at site before the installation of microwave transmission system and such RFI has to be performed at site. ODUs to be used should be sub-band free, provide such information in your proposal to identify which frequency bands are supported.
Self-freqeuncy scanning can also be defined as being able to check for the suitable point frequency to be used using the installed ODUs and having the opposite station in mute mode for transmitting, then checking at local station if interferences are observed.

 L6 to 42 GHz. ODU that is tunable to the whole frequency (subband
 free). Vendors shall state what kind of free tunable ODU can be provided. Self-frequency scan is required.
Is this a mandatory item for vendors to comply? Tunable ODU is not a common practice and does not comply with your IP66 requirement. ODUs to be used should be sub-band free, provide such information in your proposal to identify which frequency bands are supported.
ODU’s IP66 compliance is non-negotiable.
65 1.11 The proposed equipment shall support twelve (12) Radio Directions
 or above without cascade, and shall support 1+0, 2+0, 1+1
 HSB/SD/FC, XPIC Configuration.
Is (12) Radio Directions needed at day 1?  What is the minimum radio directions based on actual project requirement?

68 1.1.4. Reliability Methods: ITU-R P.530-7/8 with Fade Margin of at least 35dB (minimum). Faded margin reduced to 25db instead of 35db. Most Microwave vendors does not support 35db fade margin. Denied. Please comply to the Fade Margin (35dB) and Availability (99.99%) requirement.
69 1.1.7. Channel Spacing: Shall support between 7 to 112 MHz The TOS is old version developed in 1992, it was replaced and adapted by almost all Microwave manufacturers with RFC2474:IPv4 DSCP. We highly suggest to adapt the latest RFC2474:IPv4 DSCP instead of the old RFC1349:IPv4 TOS. DICT cannot see the relation of the inquiry to the clause.  Reference: Please comply to the stated Channel Spacing range.
70 1.1.17. Ethernet feature. The proposed equipment shall support, but not limited to, the following services and standards:
● RFC 2460: IPv6 Traffic Classes
We respectfully suggest to delete this requirement since all Microwave vendors support VLAN to classify IPv6 traffic. IPv6 DSCP compliance is also acceptable.
71 1.1.20. Priority Management, the scheduling scheme should support SP, WRR, DWRR, WFQ, SP+WRR, SP+DWRR, SP+WFQ We respectfully suggest to delete this requirement, based on our study there are only very few microwave manufacturers who can comply on this requirement. Offered MW Radio System should be able to support the listed QoS functions.  Please comply to at least four (4) of the QoS functions.
72 1.8.1. The antenna should be a dual polarized-high performance with radome. Vendor shall provide single and dual polarized antennas covering 6 to 42GHz frequency. The antenna system should withstand a wind loading of at least 300kph. Must be adaptable to the NTC allowed frequencies to be used. No tower will survive a 300Kph wind speed, it doesn’t make sense to keep the equipment in the tower if there is an incoming typhoon that packs a wind speed of 300kph. We respectfully suggest to reduce the wind speed requirement from 300Kph to 200Kph. Denied. Comply to the 300kph wind survival rating for antenna.
73 1.8.2.5. Dustproof and waterproof and must be IP66 Compliant     The antenna is passive component, it is not a practice in the industry or among microwave manufacturers to have water Ingress protection specs on the antenna. We respectfully suggest that this requirement be deleted. This item is meant for the ODUs of your MW Radio Systems.  However, the antenna are already built for outdoor use and should not be an issue.

Change to: The bidder must hold a PCAB License with Category AAA in General Engineering for a minimum of two (2) years on or before the date of the bid opening. For joint venture, at least one of the JV should comply to this requirement.  
84 1.1.6. Frequency: The equipment shall support all licensed bands L6 to 42 GHz. ODU that is tunable to the whole frequency (sub- band free). Vendors shall state what kind of free tunable ODU can be provided. Self-frequency scan is required. Is this a mandatory requirement? Usually Sub‐band free equipment would mean that diplexers of the ODU’s are field replaceable which would mean they need to be weatherproofed properly and may risk water ingress on site. The requirement being an all‐weather system should take into consideration this disadvantage. Also, usually these types of equipment would cost more and would not prove beneficial to the project’s objective. ODUs to be used should be sub-band free, provide such information in your proposal to identify which frequency bands are supported.  ODU’s IP66 compliance is non-negotiable.  Removable items, such as diplexers, are not preferred.  ODUs should have wide-band filters.
85 1.1.23. The proposed equipment shall support bandwidth notification based on ITU Standard. Is this a mandatory requirement? The equipment to be proposed would support Layer 3 services which can be used to interface to any external third‐party router. The abovementioned feature would not really be needed and would only eat up equipment resources if enabled. The offered MW Radio System should be able to support such requirement.
86 1.4. Security The proposed equipment should support SSL/SSH/SNMPV3 to guarantee the securityof management. SSL is a networking protocol used for web clients and web servers which does not apply to radio backhaul equipment, is this a mandatory requirement?
