Provides 24 channels, but a maximum of 16 channels can be used for voice lines. (Channels 9 through 24 are used for voice.) These channels can be assigned to line or pool buttons and used for incoming and outgoing calls. The eight unused (that is, unequipped) channels (channels 1 through 8), and any channels you do not use for voice lines, can be used for data connectivity by placing an external Channel Service Unit (CSU)/DSU (Data Service Unit) between the T1 module and your T1 service provider. Supported in Release 6.0 and later systems. In addition to the 6.0 software, a T1 Patch, software upgrade is required.

Features:

• Contains one RJ-45 port to connect your service provider to the T1 module
• Provides three pairs of bantam jacks (labeled Transmit, Receive, and Monitor) for maintenance testing and diagnostics
• Provides internal CSU for voice call connectivity to the T1 service provider and diagnostics

To configure and maintain a T1 module, you must use the PARTNER ACS R6.0 PC Administration software. You cannot program a T1 module via System Programming from extensions 10 or 11.
