Configuring WAN Line Services
6-6 117021-A Rev. A
Setting the Internal Clock Mode
The T1 equipment associated with a T1 interface must use a compatible transmit
clock. The T1 interface supports three sources for the transmit clock:
Internal -- Indicates that the router sets the clock
Slave -- Indicates that the incoming data stream sets the clock
Manual -- Indicates that jumpers on the T1 link or net module set the clock
You can set the Clock Mode parameter on this interface.
By default, the T1 interface uses manual clock mode, determined by hardware
configuration jumpers. Refer to Installing and Maintaining BN Routers or
Installing and Maintaining ASN Routers and BNX Platforms for information
about configuring the T1 module’s hardware jumpers.
Assigning Channel Functions
Each T1 channel on an interface is idle by default. You can assign the following
functions:
Data -- Assigns the channel to data pass-through (T1 connector to
T1 connector)
Voice -- Assigns the channel to voice pass-through (T1 connector to
T1 connector)
Circuit 1 -- Assigns the channel to the first T1 connector
Circuit 2 -- Assigns the channel to the second T1 connector
Idle -- Makes the channel idle
Circuit Assignment
You cannot allocate a T1 channel to more than one T1 circuit. For example, if you
allocate Channels 17 to 24 to Circuit 1 on the first T1 connector, you must make
these channels idle or allocate them to Circuit 2 on the second T1 connector.
