Q.SIG Prerequisite Tasks
The following configuration tasks should be completed before you configure Q.SIG on the
Cisco MC3810:
•Configure the ports used on the Cisco MC3810 as voice ports. For information on how to configure
ports to be used as voice ports, see the “Configuring Voice Ports” section in the “Configuring Voice
over ATM” chapter.
•Configure Voice over Frame Relay or Voice over ATM. For information on how to configure Voice
over Frame Relay, see the “Configuring Voice over Frame Relay” chapter. For information on how
to configure Voice over ATM, see the “Configuring Voice over ATM” chapter.
To configure Q.SIG PRI signalling support on the Cisco MC3810, use the following commands
beginning in global configuration mode:

Command Purpose
Step1 Router(config)# isdn switch-type [primary-qsig-slave
| primary-qsig-master]
Configures the ISDN switch type to serve either as
the primary Q.SIG slave or the primary Q.SIG master.
If the PINX device is the primary Q.SIG master,
configure the Cisco MC3810 to serve as the primary
Q.SIG slave. If the PINX device is the primary Q.SIG
slave, configure the Cisco MC3810 to serve as the
primary Q.SIG master.
Note You can configure the ISDN switch type
using either this global command, or this
same command in interface configuration
mode, depending on your configuration. (See
Step 3.) If you configure the global
isdn-switch-type command for Q.SIG
support, you need not also configure the
interface isdn-switch-type command for
Q.SIG.
Step2 Router(config)# interface serial 1:xEnters interface configuration mode for the ISDN
PRI interface. For T1, enter serial 1:23. For E1, enter
serial 1:15.
