PSI 16 PORT FR I/O CARD The programmable serial interface (PSI) I/O card provides 16 ports configurable as V.35, X.21 or V.28/RS-232 physical interfaces. The physical interface is a 26-pin SCSI D-shell, so appropriate adapter cables must be used for V.28, V.35 or X.21. Ref 90-6502-01..-04, 90-7004-01..-04, 90-7005-01..-04

7270 PSI 16 PORT FR CARD R4.3 This card provides High Speed Frame Relay processing. Provides ATM to FR Service Interworking and Network Interworking. Can also operate in HDLC frame forwarding mode for transparent transport of HDLC-based protocols such as X.25, SNA and PPP across the ATM network. Supports Test Access Connection (TAC) for VBR and Closed Loop Congestion Control. This card is delivered with R4.3 software.

The DS3 CE card provides the termination of a single DS3 circuit emulation interface channelized down to DS1.

DUAL MAU This Dual MAU provides redundancy connectivity between adjacent pairs of redundant Call Processing cards. This Dual MAU is mandatory if Call Processing 1+1 hot redundancy is to be used on the Call Processing cards, available in R4.0 and later. The Dual MAU is not required (for either warm or hot redundancy) with the Integrated CallP/PNNI system configuration. The IP Services Card (ISC - 90-6184-xx) uses the same Dual MAU. The Dual MAU is mandatory to interconnect two adjacent ISC's running in 1+1 Redundancy mode, available in R4.2 and later. If the MAU is missing, the working card becomes active and the secondary ISC card is neither active nor providing redundancy.

E1 120 4P VOICEBAND SERVICES CARD clei The Voiceband Services Card (VSC) terminates TDM channels at its 120 ohm E1 ports, and provides features including speech compression, silence removal, and fax demodulation to adapt these TDM channels to transport over an ATM network.
