The Frame Relay service module (FRSM) enables Frame Relay communications over an ATM network.
The FRSM cards typically connect to a Frame Relay router. Communications from the Frame Relay
router are then connected through the ATM network by a soft permanent virtual circuit (SPVC) to a
remote device.
The FRSM-2CT3 allows full n x DS0 and DS1 channelization of T3s, for a maximum of 4000 virtual
connections per module. The FRSM-2CT3 supports 256 ports per module. The FRSM-8E1-C allows full
DS0 and n x DS0 channelization of the E1s, for a maximum of 248 ports per module . The FRSM-8T1-C
allows full DS0 and n x DS0 channelization of the T1s, for a maximum of 192 ports per module. FRSM-8
supports 1000 VCs per module.
When the FRSM is combined with a back card, a card set is created. Table 2 -14 provides information
about each FRSM, interface, and corresponding back card.
