bandwitdth on Cisco 15454 Ansi shelf w/(tcc+,xc-vt) ver.4.1.3

[martin.martinez]

I have a 15454 Ansi chassis running soft. ver. 4.1.3

TCC+ - 2

XC-VT - 2

2(4 pt OC12 1 crd active 1 crd protect) - 4 ckts bidirectional

2-(OC48 1 pt 1 crd active 1 crd protect) - interconnect w/another 15454

2- (OC3 - 4pt 1 crd active 1 crd protect) - 3ports used on each card

non-bidirectional ckts

2 -(DS3 12 pt.1 crd active 1 crd protect) - 3 ckts

2 - (DS1 14 pt 1 crd active 1 crd protect) - 2 ckts bidirectional

1 - (E100 card) - 3 ckts

from this do I only have 24 STS's left on this box? I know that I cannot build any more DCC channels. This is due to the limitation of th TCC+ card.I can only provision 5 dual dcc channels. Please if anyone can help let me know.

What does your topology look like? Are you aggregating traffic from the lower speed links to the OC48, or in some ports and out others? The XCVT provides 144 bidirectional STS-1 cross connects.

In CTC node view, go to Maintenance tab, then Cross-Connect button, and the Resource Usage tab should give you some insight as to how many resources have been used on your XC card. Its numbers of 288 and 672 are for unidirectional circuits.

Hopefully this will provide you some insight, but if I can help more, please let me know.

If I am both aggregating traffic from the lower speed links to the OC48, also in some ports and out others. With the configuration that I have am I burning up 2 sts's for active ckt and 1 for protection.

I had to think on this one for awhile and look at some stuff on my own network, but it looks like you are right.

I have a node on a 2F BLSR (OC-48). It has 2 OC12 cards configured in 1+1 to another carrier. Also, I have an OC3 link (with only 1 active STS-1) configured with no protection to a customer.

According to my cross-connect matrix, I have used 37 of 288 STS-1s (144 bidirectional). All my circuits are bidirectional.

I have 4 STS-1s that come in on the OC-48 east and out the west side, that accounts for 8 of my STS-1s.

I have 1 STS-1 that comes in the OC-48 and out the OC-3, that accounts for 2.

I have 9 circuits that come in the OC-48 and out the OC-12. That uses 18 cross-connects for the working, and an additional 9 for the 1+1 protect.

8+2+18+9=37 STS-1s

While looking over some other documents on the ONS 15454, I came across one that explains the switching matrix on the XC card in depth.
