Series56 Digital Modem cards
The Series56 II and Series56 III digital modem cards provide 48 modems in a single-height
slot card that can terminate both modem and HDLC calls. However, the Series56 II and
Series56 III cards can process only calls that use a single DS0. These cards cannot process data
streams that span multiple DS0s of the same T1 or E1 interface. For this reason, Frame Relay
connections cannot use the Series56 II or Series56 III slot cards, but must use the Hybrid
Access cards instead. Series56 II and Series56 III ports appear in the output of both the HDLC
and Modem commands.
The Series56 II and Series56 III digital modem cards have identical panels as shown in
Figure A-14.
