Table 6: T1 Connector Wiring
The Allworx 48x is designed for T1 “short haul” use and has a fully integrated Channel Service Unit / Data
Service Unit (CSU/DSU). An external CSU/DSU is not required and should not be used. The Allworx 48x
should be connected directly to the on-site smart jack or local T1 device using the proper cabling. Do not
connect the Allworx 48x directly to the "long haul" wire pairs exiting the building.
Note: Do not plug any network or ISP service into the server without first properly configuring the server.
Failure to heed this warning may result in a disruption of network connectivity with other equipment on
the network.
After the unit is properly configured, the T1 network infrastructure cables can be plugged in. Standard RJ-45
T1 cables must be used.
The LED’s on the T1 ports are defined in Table 7.
