AS5400 capacity

we have a AS5400 already installed a CT3 card, but only use 12 T1. So can we install other two 8CT1 card on this service to use together(because we have a contract with different telecom service provide)?

Re: AS5400 capacity

Which exact 5400 model do you have ?

20 x T1 on a single box seems a bit high, you might consider getting a second router for the new circuits.

Re: AS5400 capacity

we have a Cisco AS5400HPX, it's max capacity is 28T1, I want to know if it is possible we can use 12T1 on one CT3 card together with another 16T1 on another two 8CT1 cards on the same box?


Re: AS5400 capacity

The above is not doable because:

- the HPX has 7 slots in total

- you are using 1 for CT3 and 2 for 8CT1

- in the remaining 4 slots if you add DSP cards, you get 4 * 108 = 432 max

- Hence you can only go upto 432/24 = 18 T1s total

If you use the newer AS5400XM, this is doable, as that box has higher DSP densities per slot. I see there is a trade in program for this if you are interested:
