Configuring ISDN
12-8 PortMaster Configuration Guide
Multiple Subscriber Network for an S/T Interface
For countries that support BRI via the S/T bus interface, you can enable the multiple
subscriber network (MSN) feature. When enabled, this feature allows multiple ISDN
devices attached to the same BRI line to receive calls not intended for the PortMaster.
When the MSN feature is disabled, the PortMaster rejects the call if a port is not
available. In this case other S/T connected devices are not given an opportunity to check
or accept the call. This is the default.
To enable the MSN for an ISDN S/T interface, enter the following command:
Command> set isdn-msn on
Port Limits
You can set port limits on a per-user basis for Multilink V.120, Multilink PPP, and
asynchronous multiline load balancing users. If a port limit is set, the user is limited to
that number of ports on the PortMaster. If the number of dial-in ports is left
unconfigured, port limits are not imposed and the PortMaster’s multiline load balancing,
Multilink V. 120, and Multilink PPP sessions are allowed. You can also configure this
setting using the RADIUS Port-Limit attribute.
To set port limits, use the following command:
Command> set user Username maxports Number
Data over Voice
Data over voice is supported for inbound and outbound ISDN connections. The
PortMaster accepts inbound voice calls and treats them as data calls.
To force a data-over-voice call for an outbound ISDN connection, use the following
command:
Command> set location Locname voice on | off
