Configuring E1 and T1 Services
308648-14.00 Rev 00
6-11
By default, the E1 interface uses manual clock mode, which is determined by
hardware configuration jumpers. See Installing and Maintaining BN Routers or
Installing and Maintaining ASN Routers and BNX Platforms for information
about configuring the E1 module’s hardware jumpers.
See the Clock Mode parameter on page A-11 for information.
Assigning Channel Functions
Unless you change the default channel function, each E1 channel on an interface
is idle by default.
You can assign these functions:
• Data -- Assigns the channel to data pass-through (E1 connector to
E1 connector)
• Voice -- Assigns the channel to voice pass-through (E1 connector to
E1 connector)
• Circuit 1 -- Assigns the channel to the first E1 connector
• Circuit 2 -- Assigns the channel to the second E1 connector
• Idle -- Makes the channel idle
Circuit Assignment
You can allocate an E1 channel to only one E1 circuit. For example, if you allocate
channels 17 to 25 to circuit 1 on the first E1 connector, you must make these
channels idle or allocate them to circuit 2 on the second E1 connector.
Data and Voice Pass-Through
To enable data and voice pass-through, assign identical channels to data or voice
on both E1 connectors.
For example, if the first E1 connector allocates channels 2 to 8 to voice
pass-through and channels 9 to 16 to data pass-through, the second E1 connector
must also allocate channels 2 to 8 to voice pass-through and channels 9 to 16 to
data pass-through.
