276 ISDN Port Configuration
28.2 Warnings
Port activation deactivation
ISDN ports can only be configured when in the down state. The first configuration task explains how
to disable and enable ISDN ports for configuration. When the port is down all active calls on the port
are dropped. This operation must only be performed during planned down times.
Reference Clock Source and Synchronization
The SmartNode uses a single reference clock source for the synchronization of the 64kbit/s PCM
channels on the ISDN ports and in the CS context. This reference clock source can be internal or
derived from one of the ISDN ports. If the clock reference is not configured in accordance with the
network environment, clock slips and related voice quality degradations can occur. Refer to Chapter
24 , “ CS Context Overview ” on how to configure the reference clock.
Connector Pinout and Short circuits
Some of the SmartNode ISDN BRI ports are configurable to operate as network or terminal ports.
The pinout of the sockets is switched according to this configuration. Wrong port configurations,
wrong cabling or wrong connections to neighboring equipment can lead to short circuits in the BRI
line powering. Refer to the HW installation guide and the port configuration sections bellow to avoid
miss configurations.
28.3 ISDN Port Configuration Task List
Configuring ISDN ports typically consists of the following tasks:
• Shutdown and Enable ISDN ports
• Configure common BRI and PRI parameters
• Configure BRI port parameters
•
Configure PRI port parameters
28.4 Shutdown and Enable ISDN Ports
Prior to changing any configuration settings on an ISDN port, the port must be shut down. You can
perform all configuration tasks and then activate the port, so activating all your configuration
changes.
