Figure 28 High-Speed Serial Cables Connected to the 2T16S Network Processor Module
Making Low-Speed Serial Connections
The 16 low-speed serial ports use two 200-pin D-type connectors. Use the specific serial transition cable
for the module type and the correct connector for your modem or CSU/DSU connector type.
Because of the bulk of the low-speed serial cables, a cable support tray must be used in conjunction with
the 2T16S network processor module. (See Figure 21.)
Step 1 Attach the ends of your serial transition cables to the synchronous serial ports of the serial network
processor modules. (See Figure 29.)
Step 2 Allow enough play in the transition cable for a service loop, then attach the transition cable to the cable
support tray using the U-shaped clamps. (See Figure 24 on page 29, Figure 25 on page 30, and Figure 30
on page 35.)
