Administering E1 and T1 Services
Using terminal-server commands
Connection profile, you must move to the Call profile (Host/6 > Port N Menu > Directory) or
the Connection profile and press Ctrl-D 1.
You cannot dial if

is set to
No
for the control port. If a call is already active, DO
2 (Hang Up) appears instead of DO 1 (Dial). If the T1 or E1 line is not available, Trunk Down
appears in the message log and you cannot dial.
To verify that the profile is correctly configured:
1
Make certain that you have entered the correct telephone number to dial.
2
Verify that the Data Svc parameter specifies a WAN service available on your line.
If you request a WAN service that is not available on your line, the WAN rejects your
request to place a call.
3
Check whether the channels using the requested WAN service are busy.
If these channels are busy, an outgoing call might be routed to channels for which you did
not request the specified WAN service. Check the Data Svc, Call-by-Call, and PRI # Type
parameter values in the profile.
4
Determine whether you have correctly set the parameters controlling Dynamic Bandwidth
Allocation.
For detailed information, see the Network Configuration Guide for your unit.
Using terminal-server commands
Terminal-server CLI commands can display information directly related to, or temporarily
affecting, the performance of the unit’s the E1/PRI and T1/PRI interfaces. Use the
terminal-server command-line interface to test and reset the MAX unit. Verify clock source
settings the MAX unit.
For more information about how to use the terminal-server command-line interface, see
Chapter 3, “Terminal-Server Administrative Tasks.”
Resetting the unit and clearing calls
The Sys Reset command restarts the MAX unit and clears all calls without disconnecting the
device from its power source. The unit logs out all users and returns user security to its default
state. In addition, the unit performs diagnostic power-on self tests (POSTs) when it restarts. A
system reset of a MAX unit causes momentary loss of T1 framing (that is, the
data-encapsulation format), and the T1 line might shut down. In any event, the feedback from
the MAX unit to the switch is incorrect until T1 framing is reestablished, usually within 30
seconds. If you have enabled the integrated CSU on the MAX unit that you are testing, you
must notify your E1/PRI or T1/PRI carrier before you turn the unit off. For more information,
see “Integrated CSU for T1/PRI” on page 5-4.
Displaying the source of clocking
The Clocksource command displays the source of clocking for the MAX unit. Clock slips can
cause connectivity problems, particularly for analog users. If you have used the Clock Source
parameter, in the Line Config menu’s Line N profile, use the clocksource command to validate
your changes.
