4.5 Install Analog Telephony Ports
Use the server analog phone connections to connect Central Office (CO) lines or telephone handsets.
The Connect server provides surge protection internally on all telephony interfaces.
4.6 Install the T1 Line
This feature is available on the Connect 731 server only. The T1 interface pin-outs for typical service
connections may require either a straight through cable or a cross-over cable. Verify the cable is a
shielded cable.

The Connect server is for T1 “short haul” use and has a fully integrated Channel Service Unit / Data
Service Unit (CSU/DSU). Plug-in the Connect server directly to the on-site smart jack or local T1 device
using the proper cabling. Do not connect the Connect server directly to the "long haul" wire pairs
