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 5-4 shows 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.
