Configuring T1 Cards
Enabling a line
Enabling a line
By default each T1 line is disabled. To enable the T1 line, read its profile to make it the working profile, then set the Line Interface subprofile’s Enabled parameter to Yes, as in the following example:
admin> read t1 {1 2 1}
T1/{
admin> set line enabled = yes
admin> write
T1/{
Specifying the framing and encoding
You must specify the framing and the encoding for each T1 line. If you are using ISDN, you must specify the extended superframe (ESF) format, which consists of 24 consecutive frames, separated by framing bits. If the line is not configured for ISDN signaling, use D4 framing (also known as the superframe format), which is the default.
The T1 Encoding value sets the
Your T1 service provider must provide the correct framing and encoding values for your lines.
To specify the framing and encoding, set the
admin> read t1 {1 2 1}
T1/{
admin> set line
admin> write
T1/{
Configuring ISDN PRI signaling
When you set the signaling mode to ISDN, you must set channel 24 as the D channel. Note that ISDN signaling often requires ESF framing and B8ZS encoding.
For ISDN signaling you must also specify the type of switch providing T1/PRI service to your TAOS unit. Obtain the information from your ISDN carrier. (For example, if your carrier is AT&T, the switch type is
Configure ISDN PRI service as follows:
admin> read t1 {1 2 1}
T1/{
admin> set line
