Customizing WAN Interfaces
114078 Rev. A 4-11
HDB3S support is disabled by default. You can enable or disable High-Density
Bipolar Coding on this interface, depending on the ability of the associated E1
equipment to support HDB3S.
Setting the Clock Source
The E1 equipment associated with an E1 interface must use a compatible transmit
clock. The E1 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 E1 link module set the clock.
By default, the E1 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 on
configuring the E1 module’s hardware jumpers.)
You can set the Clock Mode on this interface.
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
