Central Office Alarm Interface
The CO alarm interface is a 10-pin connector for up to three dry-contact relay switches for connection to a
CO alarm monitoring panel. The three Normally Closed alarm relays can be wired to support Normally Open
or Normally Closed devices, indicating minor, major, and critical alarms.
A CO alarm cable is shipped with the product so you can connect the CO Alarm interfaces on the SPIO card
to your alarming devices. The "Y" cable design ensures CO alarm redundancy by connecting to both primary
and secondary SPIO cards.
Redundancy Crossbar Card (RCC)
The RCC uses 5 Gbps serial links to ensure connectivity between rear-mounted line cards and every non-SMC
front-loaded application card slot in the system. This creates a high availability architecture that minimizes
data loss and ensures session integrity. If a packet processing card were to experience a failure, IP traffic
would be redirected to and from the LC to the redundant packet processing card in another slot. Each RCC
connects up to 14 line cards and 14 packet processing cards for a total of 28 bidirectional links or 56 serial
2.5 Gbps bidirectional serial paths.
The RCC provides each packet processing card with a full-duplex 5 Gbps link to 14 (of the maximum 28)
line cards placed in the chassis. This means that each RCC is effectively a 70 Gbps full-duplex crossbar fabric,
giving the two RCC configuration (for maximum failover protection) a 140 Gbps full-duplex redundancy
capability.
The RCC located in slot 40 supports line cards in slots 17 through 23 and 26 through 32 (upper rear slots).
The RCC in slot 41 supports line cards in slots 33 through 39 and 42 through 48 (lower rear slots):
