Carrier Access SNMP manual Pin Assignments for CAC V.35 Data Cables

V.35 DCE Data Port Connections

This cable is used to connect the Access Bank II SNMP V.35 DCE data port (Figure 5-3) to synchro- nous V.35 DTE data sources up to 1.536 Mbps, all rates (1-24) Nx56 or Nx64 channel-rate progres- sion. The CAC V.35 Data Cables are built according to the pin assignments listed below in Table 5-5. Figure 5-4shows the pin layout of the standard 34-pin V.35 Winchester connector typically used to connect to Routers and FRADs.

To connect the CAC V.35 data cable to the V.35 DCE data port, connect the end with the 26-pin micro-D male connector to the Access Bank II SNMP V.35 DCE data port and the end with the 34- pin Winchester male connector to the V.35 DTE data source.
