Configuring SVCs

CoreBuilder 7000 family ATM switches use standard UNI 3.0, 3.1 or 4.0 switched virtual channel (SVC). SVC mode can be used when CoreBuilder is in a backbone or workgroup topology, with PVC used whenever necessary. ILMI enables automatic address registration for SVC. Addresses can be registered manually via the LMA menus.

Changing the UNI Version

The CoreBuilder will run UNI 4.0 SVC by default. You can work in UNI 3.0 or UNI 3.1 by choosing this option in the signalling setup menu.

Configuring Network Prefix and ATM Addresses

ATM addresses are essential for establishing a connection using SVC. Most devices that support SVC, also support automatic address registration through the ILMI protocol.

A network prefix is essential for address registration to be executed. Refer to CoreBuilder 7000 Family ATM Switches Management Guide for proper network prefix setting.

For connectivity with devices that do not support ILMI, ATM addresses can be set manually using the Add ATM address function under ATM address setup in the Administration Console menus.

Configuring a PVC

Permanent Virtual Channels (PVC) can be used to connect to devices that do not support switched virtual channels (SVC) standard protocols. In the CoreBuilder 7000 family ATM switch you can create point-to-point (P2P) and point-to-multipoint (P2M) connections. Use the Setup and Configuration Connections menu, to create a PVC call, PTP or PTM. You can also create an out VC in a PTM call, release a PVC call, release an out VC from call, save PVC connections in flash memory and reset saved connections. Up to 2000 PVCs can be configured.

Configuring Clock Synchronization

External clock synchronization allows a clock to be received on one of the bottom of 4 OC-3c ports of an 8-port interface card from an external source, and to be distributed to all bottom OC-3c ports on the same card and other 8-port interface cards in the same chassis. It is used in voice and data applications so that the same port is used at the same time. You can configure one port to be the master port which will distribute its
