Tip To save the gateway configuration, save it to NVRAM. See the “Saving Configuration Changes” section on page 60.
Verifying the Firmware Upgrade
To verify your firmware upgrade, use the show voice dsp version command.

Configure Clocking
The time-division multiplexing (TDM) bus on a Cisco AS5350XM or Cisco AS5400XM universal gateway backplane can
receive an input clock from one of four basic sources on the universal gateway:
• A T1 or E1 feature card
• A CT3 feature card
• An external T1/E1 clock source feed directly through the building integrated timing supply (BITS) interface port on the
motherboard
Note A BITS is a single building master timing supply. The BITS generally supplies DS1- and DS0-level timing throughout
an office. In North America, the BITS is the clock that provides and distributes timing to a wireline network’s lower
levels.
• A free-running clock that provides a clock from an oscillator
Feature Card Ports
The TDM bus can be synchronized with any feature cards. On the CT1/CE1 feature cards, each port receives the clock from the
T1/E1 line. The CT3 feature card uses an M13 multiplexer to receive the DS1 clock. Each port on each feature card trunk slot
has a default clock priority. Also, clock priority is configurable through the dial-tdm-clock priority
CLI command.
