Chapter 4 Optical Cards
4.18.2 Ports and Line Rates
The maximum bandwidth of the 15454_MRC-12 card is determi ned by the cross-connect card, as shown
in Table 4-19.
4.18.2 Ports and Line Rates
Each port on the 15454_MRC-12 card can be configured as O C-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 4-19, the following rules apply for various
synchronous transport signal (STS) available bandwidths. (Table 4-20 shows the same information in
tabular format.)
STS-12
Port 1 is the only port that is usable as an OC-12. If Port 1 is used as an OC-12, all other ports
are disabled.
Ports 1, 4, 7, and 10 are the only ports usable as OC-3. If any of these ports is used as an OC-3,
Ports 2, 3, 5, 6, 8, 9, 11, and 12 are disabled.
STS-48
Port 1 is the only port usable as an OC-48. If Port 1 is used as an OC-48, all other ports are
disabled.
Ports 1, 4, 7, and 10 are the only ports usable as OC-12.
If Port 4 is used as an OC-12, Ports 2 and 3 are disabled.
If Port 7 is used as an OC-12, Ports 5, 6, and 8 are disable d.
If Port 10 is used as an OC-12, Ports 9, 11, and 12 are disable d.
Any port can be used as an OC-3 as long as all of the above rules are followed.
STS-192
Ports 1, 4, 7, and 10 are the only ports usable as OC-48.
If Port 4 is used as an OC-48, Ports 2 and 3 are disabled.
If Port 7 is used as an OC-48, Ports 5, 6, and 8 are disable d.
If Port 10 is used as an OC-48, Ports 9, 11, and 12 are disable d.
If Port 4 is used as an OC-12, Ports 2 and 3 can be used as an OC-12 or OC-3.
If Port 7 is used as an OC-12, Ports 5, 6, and 8 can be used as an OC-12 or OC-3.
If Port 10 is as used as an OC-12, Ports 9, 11, and 12 can be used as an OC-12 or OC-3.
If Port 4 is used as an OC-3, Ports 2 and 3 can be used as an OC-3 or OC-12.
If Port 7 is used as an OC-3, Ports 5, 6, and 8 can be u sed as an OC-3 or OC-12.
