Additional FTTC CAB


[link to this post]
 
Just seen an additional 288 port FTTC CAB being installed close to the existing 128 port that we are connected to. I wonder if this will complement the existing arrangement's or replace the existing CAB all together?

The additional cabinet has likely been installed due to the 128-line cabinet being full and customers on the PCP still looking for FTTC products (To increase capacity).

It would mean a serious misjudment of the take-up of FTTC if BTO installed a 255 FTTC CAB in addition to a 128 CAB already commisioned!

The logical options are a second 128 CAB, replace the 128 with a 255 288 (both giving twice the capacity) or an additional 255 288 CAB which would triple the original capacity!

Obviously depends on the number of lines supported by the PCP and the distance from the exchange (easier to sell FTTC in areas with 1Mb/s or less than those who already receive 20Mb/s via ADSL!).

EDIT: replace 255 with 288 blush

FTTC Cab installation commenced 12th April - expect full 80 / 20 - bye bye BE, hello BT Infinity soon!

Theirs a local cab near me that has both a 128 and 288 line cab installed next to it for extra capacity.

It is in a VM area, which could be why only the 128 was installed initially and then the larger 288 when demand increased.

I have also see 2 288 cabs next to one pcp but this is due to cab placement as another pcp is under 50 meters away on a small path.

What make is the 255 cab? The big Huawei is 288.

In reply to a post by RobertoS:

I made the mistake of stating 255 - the OP correctly said 288 blush

128 is logical in computer terms, 255 would be (1 less than 256) but 288 seems a strange number confused

Had me wondering if there was a 255 ECI smile.

288 is 6 cards of 48 ports each.

Cards sizes often move from 16 ports to 32 ports to 48 ports to 64 ports. Huawei seem to have 48port ones at present

With 4 Ge ports and a minimum 15Mb giving 264 ports. the dimensioning works out about right. Some ports will have products with less than 15Mb minimum on making it possible to use all 288 with a bit of luck. I wonder if the ECI 128 port cabs are 4*32port cards or 2*64 port cards ?
