56K/64K NIM COMMANDS

clock rate {auto | bps56k | bps64k}

Configures the data rate used as the operating speed for the interface. This rate should match the rate required by the DDS service provider.

auto

bps56k Sets clock rate for 56 kbps.

bps64k Sets clock rate for 64 kbps.

clock source {internal | line} Configures the source timing used for the interface.

internal Provides clocking using the internal oscillator.

line

data coding scrambled

Combines user data with pattern data to ensure user data does not mirror standard DDS loop codes (used only on 64 kbps circuits without frame relay signaling).

description <text> Comment line to provide an identifier for this interface (for example, circuit ID, contact

information, etc.)

<text> Up to 80 alphanumeric characters

loopback {dte | line | remote} Initiates a loopback on the interface. The no version of this command deactivates the

loopback.

dte Initiates a loop to connect the transmit and receive path

line Initiates a loop of the DDS circuit towards the network by

remote Transmits a DDS loop code to the remote unit. In response,

Detects clock rate on line and sets to match.

Recovers clock from the circuit.

through the unit loop.

connecting the transmit path to the receive path.

the remote unit should initiate a line loopback.

remote-loopback

Configures the interface to respond to loopbacks initiated by a remote unit (or service provider).

The no version of this command configures the interface to ignore DDS loop commands.

shutdown

Turns off the interface. The no version of this command turns the interface on and allows it to pass data.

snmp trap

Enables all supported Simple Network Management Protocol (SNMP) traps on the interface.

snmp trap link-status

Controls the SNMP variable to enable (or disable) the interface to send SNMP traps when there is an interface status change.

* Indicates default values.
