5 Enable the connector, using:
SETDefault !<path> -PAth ConnControl = Enabled
Connector parameter settings are not applied until the connector is
enabled.
This section describes how to configure Ultra-WAN CSU/DSU interface for
multiple path, channelized service.
To configure the Ultra-WAN CSU/DSU interface, follow these steps:
1 Set the FrameMode as appropriate for your setup:
SETDefault !<path> -PAth FrameMode = T1_SF | T1_ESF | E1_CRC4 |
E1_NOCRC
where <path> = 4A, 4B, 4C, or 4D.
The FrameMode parameter allows you to specify the frame mode. The
allowable values are the following:
T1_SF Superframe format T1.
T1_ESF Extended Superframe format T1.
E1_CRC4 CRC-active E1.
E1_NOCRC E1 without an active CRC.
2 Set the connector type as appropriate for your setup using:
SETDefault !<path> -PAth CONNector = E1_Channelized
|T1_Channelized
where <path> = 4A, 4B, 4C, or 4D.
