Configuring E1 and T1 Interfaces
Viewing Information about E1 and T1 Interfaces
The first line indicates whether the interface is up or down. The second line
lists alarms, if there are any. The next two lines show current configurations
for line coding, framing, and clock source. For T1 interfaces, the FDL type and
the line build out settings are also listed. If the line is in loopback, this
information is listed as well.
The channels are listed as a series of digits: for an E1 interface, the channels
are listed as 0-9, 0-9, 0-9, and 1. As shown in Figure 4-7, the first channel 0 is
reserved for framing. For a T1 interface, the channels are listed as 1-9, 0-9,
and 0-4.
Underneath the digits, a series of Ns or dashes indicate how the channels are
being used. Channels marked with N are dedicated to the E1- or T1-carrier
line. Channels that are marked by a – are not being used.
Although the E1 interface shown in Figure 4-7 has been configured to use
channels 1-31, these channels do not appear to be allocated to the line. The
channel assignment is not displayed correctly until you properly configure the
Data Link Layer protocol. After the protocol is configured for the E1 or T1
interface, the show interfaces command will indicate that the channels are
allocated. (For more information, see Chapter 6: Configuring the Data Link
Layer Protocol for E1, T1, and Serial Interfaces.)
If you are configuring an E1 interface for an E1 + G.703 module, the channels
that you do not allocate to the E1 interface are marked with a D and are
allocated to the G.703 interface. Likewise, if you are configuring a T1
interface for a T1 + DSX-1 module, the channels that you do not assign to the
T1 interface are marked with a D and allocated to the DSX-1 module.
N o t e
By default, all channels are allocated to the G.703 or DSX-1 interface until you
change this configuration. For more information about allocating channels to
the G.703 or DSX-1 interface, see Chapter 9: Configuring the E1 + G.703 and
T1 + DSX-1 Modules.
As Figure 4-7 shows, the section under the channel assignment displays the
line status and informs you of any alarms.
