Additional Switch Configuration 73
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
