Connector-level
Path Parameters

CLock

Syntax
Default
Description

CONNector

Syntax
Default
Description
Specifically, it is <nm> where n = 3 or 4 (and indicates the connector
grouping) and m = a,b,c, or d (and indicates the connector/path).
This section describes connector-level path parameters applicable to
Ultra-WAN CSU/DSU connectors on the model S590/S598 PathBuilder
switches.
SETDefault !<path> -PAth CLock = External | Internal
SHow [!<path> | !*] -PAth CLock
SHowDefault [!<path> | !*] -PAth CLock
External
The CLock parameter selects the clock source for the connector
transmitter. External is used for normal operation, indicating that the
transmit clock will be derived from the receive clock. Internal is for test
purposes, or in rare system topologies where the Ultra-WAN CSU/DSU
connector needs to source the system clock. When Internal is selected,
the transmit clock is derived from an onboard oscillator.
Before changes to this parameter can take effect a "SETDefault !<path>
-PATH ConnControl=Enable" command needs to be issued on the
corresponding connector.
SETDefault !<path> -PAth CONNector = [E1_Unstructured |
T1_Unstructured | E1_Pri | T1_Pri | E1_CHannelized |
T1_CHannelized ]
SHow [!<path> | !*] -PAth CONNector
SHowDefault [!<path> | !*] -PAth CONNector
none
The CONNector parameter specifies the connector type for an Ultra-WAN
CSU/DSU and Flex-WAN serial interfaces.
Before changes to this parameter can take effect, a "SETDefault !<path>
-PAth ConnCONTrol = Enable" command needs to be issued on the
corresponding connector.
