[c-nsp] PA-MC-T3 and capacity questions

Hi Matt,

Back in October you had recommended using the ONS system described below. I
was wondering if you or anyone on this forum could look over the items below
and see if anything is missing to complete this system?

2X 15454-TCC+
1X 15454 NEBS3 Chassis
1X 15454-FTA
2X 15454-DS3XM-6
2X 15454-XC-VT
1X 15454-EIA-BNC-B24

Thanks,

Troy Beisigl

Cross connecting DS1s-wise, you may want to look into the Cisco ONS
15454 line. Get yourself a shelf, the BNC electrical interface cards, 2x
TCC+'s, 2x XC-VTs, and 2x DS3-XM6 cards (6 port DS3 transmux). You could
also then add on a 4 port OC-3 card to map the incoming DS1s inside a
DS3 or an OC-3 onto an outgoing DS3 or an OC3.

Most of the gear I just mentioned is EOL/EOS now though (except the
shelf), but can be found fairly cheaply (except maybe the XM6s) on the
secondary market.

Hi,

 

I have 2 quick questions about capacity issues when using PA-MC-T3 cards
and
the ability to do MLPPP. We currently have 5 PA-MC-T3 cards in a
7507/RSP8
chassis and I would like to be able to move onto either a higher
capacity
chassis or split things between two chassis. If we go the route of
multiple
chassis, I would need something like a M313 MUX that could take 6 or
more
DS3 circuits in and re-map them to different channels on DS3 ports
coming
out to the different chassis. This is due to the MLPPP needs and
multiple
carriers these circuits are coming from. If we go with a larger capacity
chassis, I am thinking of changing over to OC3c circuits from the
carriers
to ensure that we would not have capacity issues down the road.

 

So my questions are,

 

A.	What would be the recommended M313 MUX for this in the case of
split
chassis?
B.	Going with a larger capacity chassis, what would be recommended
for
doing this via OC3c handoffs or would it be better to stay with CT3
ports?

 

 

Thanks.

 

-Troy
