Catalyst 6500 Series 24-Port FXS Analog Interface Module Installation Note
78-10975-02
Features
Hot Swapping
Hot swapping lets you remove and replace the 24-port FXS analog interface module while the system is
operating. When the system detects that a module has been installed or removed, it automatically runs
diagnostic and discovery routines, acknowledges the presence or absence of the module, and resumes
system operation without any user intervention.
Power Management
Because the Catalyst 6500 series modules have different power requirements, certain switch
configurations require more power than a single power supply can provide. Although the power
management feature allows you to power all installed modules with two power supplies, redundancy is
not supported in this configuration.
Port Used for Modem
Calls
Optimizes the performance of modem calls. If this
parameter is enabled and the parameters for voice
and fax calls are disabled, the port is configured to
accept only modem calls. Enabling this parameter
improves the performance of the port by reducing or
removing the switchover time required to move
from voice mode to modem mode. Enable this
parameter only if you are certain that a port will
handle modem calls only
Checkbox checked
Enabled Port Used for
Fax Calls
Optimizes the performance of fax calls. If this
parameter is enabled and the parameters for voice
and modem calls are disabled, the port is configured
to accept only fax calls. Enabling this parameter
improves the performance of the port by reducing or
removing the switchover time required to move
from voice mode to fax mode. Enable this
parameter only if you are certain that a port will
handlefax calls only
Checkbox checked
Named service event
(NSE) type
NSE type attempts to standardize the transfer of
tones over real-time transport protocol (RTP). Two
NSE standards exist in Cisco products: one for
Cisco IOS gateways and one for non-Cisco IOS
gateways. The Catalyst 6500 Series Switch 8-port
T1/E1 PSTN interface module supports both
standards. You need to configure the right NSE type
based on the network setup. If the module needs to
talk to a Cisco IOS gateway (a VG200 or AS5300
for example), set this option to IOS Gateway. If the
gateways need to talk to other non-Cisco IOS
gateways (such as a WS-X6608-E1/T1, VG248, or
another WS-X6624-FXS), set this option to
non-IOS Gateway.
