OCTAL E1-2 PRI CR W/CPU-2 120 OHM This 120 Ohm card utilizes the CPU-2 and provides eight E1 ports for Cell Relay (ATM) services on the 7470, with 32k cell buffering per card and advanced traffic management capability. This card allows an optional upgrade

OCTAL E1-2 PRI CR W/CPU-2 120 OHM This 120 Ohm card utilizes the CPU-2 and provides eight E1 ports for Cell Relay (ATM) services on the 7470, with 32k cell buffering per card and advanced traffic management capability. This card allows an optional upgrade module (90-4672-01)to provide up to four groups of ATM Inverse Muliplexing. Physical connection via RJ-45, wire-wrap, or standard 50-pin Telco connector can be supported. RJ-45 connection requires a PRI RJ-45 Distribution Panel (90-2543-01) and associated 8-port cable (90-2767-xx) for each card. Wire-wrap connection requires one wire-wrap MAU(90-2542-02) per card and the 50-pin connector requires one Telco MAU (90-2542-01) per card.
