T1 INTERFACE CARD CONFIGURATION
After the T1 Interface Card has been installed in the TVS, it then must be configured using the T1
Edit program in the Tel-Site system management application. After this has been completed, the
VS1 Editor program must be used to enable the VS1 phone system to recognize the T1 Interface
Card.
T1 Interface Card Parameter Setup Using Tel-Site
1. Use Tel-Site to gain access to the Telecor VS1 phone system.
2. Click the T1 Edit button in the Configuration window of Tel-Site to open the T1 Properties
dialog box. The T1 Properties dialog box contains four tabs: Signaling, Basic, Timing and
Advanced.
• Use the Signaling tab to set the signaling type for each channel on the T1 Interface Card
based on the information provided by the Service Provider.
• Select the Basic tab to set the framing for the T1 Interface Card. Framing is used by the T1
Interface Card to synchronize with the Service Provider. If the correct framing is not
selected, the T1 Interface Card cannot carry voice information. The framing required and
its associated configuration is determined by the Service Provider.
• The Timings tab is used to set the timing parameters for the T1 Interface Card.
• The settings on the Advanced tab rarely require adjustment and should only be changed at
the direction of Telecor Technical Support.
3. Select the Signaling tab on the T1 Properties dialog box. Use the T1 Card text box to select
the T1 Interface Card for which you want to set signaling types. All ports and their signaling
status for the T1 Interface Card selected are listed in the Channels group box. You can set each
port individually; click the Select All button to set all ports; or select ports you do not want to
set, and then click the Invert Selection button to select all other ports. To change the signaling
status for a port, click one of the following option buttons in the Channels group box:
• Disabled—Select Disabled when this port of the T1 Interface Card is not used.
• E&M—E&M is the preferred method of signaling for DID ports. E&M signaling must be
set when DID, DNIS or ANI service is provided by the Service Provider.
• Loop Start FXS or Loop Start SAS—These signaling methods are not recommended
because a disconnect signal is not generated by the Service Provider. The use of FXS
versus SAS depends on the Service Provider. FXS stands for Foreign Exchange Station.
SAS stands for Special Access Station.
• Ground Start FXS or Ground Start SAS—Use these signaling methods when DID or
DNIS service is not being used. The use of FXS versus SAS depends on the Service
Provider. FXS stands for Foreign Exchange Station. SAS stands for Special Access Station.
• Mixed settings—Mixed settings Enables you to select mixed settings.
Note Reserved ports are not displayed and their settings cannot be changed.
