Traffic provisioning
Parameters for provisioning a cross-connection with SNC
protection
...................................................................................................................................................................................................................................
The following parameters are used to provision cross connections without protection.
Capacity
The capacity of the cross-connection: This can be VC-4, VC-3, or VC-12.
Cross Connection type
The following types of cross connections are possible:
• Standard: this is a cross-connection without protection.
• SNC: a cross-connection with SNC protection.
Directionality
Uni: unidirectional or Bi: bidirectional
Important! The 1643 AM or 1643 AMS only supports unidirectional
cross-connects.
Termination Points (TP)
The cross connections are made between termination points. The From, To and
Protection columns are used to select these termination points. The Protection area is
greyed out if standard is selected as Cross Connection Type.
For unprotected cross connections it makes no difference which TP is selected in the
From and which TP is selected in the To list.
For a loopback connection, the direction is always unidirectional and the termination
points in the From and To list are the same.
The termination point is selected by the Slot and Port where the termination point
belongs to. The AU4# is 1 for STM-1 ports. AU# can be 1, 2, 3 or 4 for STM-4 ports.
Example:
Existence
A Virtual termination point is a point which is not connected to a physical unit. These
points are used to implement cascaded cross connections. All other termination points
are Real
