4.15.1 Slot Compatibility by Cross-Connect Card
4.15.1 Slot Compatibility by Cross-Connect Card
You can install 15454_MRC-12 cards in Slots 1 through 6 and 12 through 17 with XC-VXL-2.5G,
XC-VXL-10G, or XC-VXC-10G cards.
Note The 15454_MRC-12 card supports an errorless software-initiated cross-connect card switch when used
in a shelf equipped with XC-VXC-10G and TCC2/TCC2P cards.
The maximum bandwidth of the 15454_MRC-12 card is determined by the cross-connect card, as shown
in Table 4-16.
4.15.2 Ports and Line Rates
Each port on the 15454_MRC-12 card can be configured as OC-3/STM-1, OC-12/STM-4, or
OC-48/STM-16, depending on the available bandwidth and existing provisioned ports. Based on the
cross-connect card and slot limitations shown in Table 4-16, the following rules apply for various
synchronous transport signal (STS) available bandwidths. (Table 4-17 shows the same information in
tabular format.)
VC4-16
Port 1 is the only port usable as an STM-16. If Port 1 is used as an STM-16, all other ports are
disabled.
Ports 1, 4, 7, and 10 are the only ports usable as STM-4.
If Port 4 is used as an STM-4, Ports 2 and 3 are disabled.
If Port 7 is used as an STM-4, Ports 5, 6, and 8 are disabled.
If Port 10 is used as an STM-4, Ports 9, 11, and 12 are disabled.
Any port can be used as an STM-1 as long as all of the above rules are followed.
VC4-64
Ports 1, 4, 7, and 10 are the only ports usable as STM-16.
If Port 4 is used as an STM-16, Ports 2 and 3 are disabled.
If Port 7 is used as an STM-16, Ports 5, 6, and 8 are disabled.
If Port 10 is used as an STM-16, Ports 9, 11, and 12 are disabled.
If Port 4 is used as an STM-4, Ports 2 and 3 can be used as an STM-4 or STM-1.
If Port 7 is used as an STM-4, Ports 5, 6, and 8 can be used as an STM-4 or STM-1.
If Port 10 is as used as an STM-4, Ports 9, 11, and 12 can be used as an STM-4 or STM-1.
