DSX-1 Interface
The DSX-1 interface is located on the rear of the Total Access 900 Series products. It is labeled
DSX-1 T1 0/1 on the ADSL units and DSX-1 T1 0/2 on all other units. The DSX-1 interface allows
DS0s to be provided to customer’s voice terminating equipment such as a PBX.
Configuring the DSX-1 Interface
The following steps demonstrate configuring the DSX-1 connection. In the following steps,
please substitute 1 (ADSL units) or 2 (all other units) for x in t1 0/x.
1. Start a VT100 terminal session to connect to your unit. If you need assistance, follow the
steps in the Total Access 900 Series Quick Configuration Guide (P/N 61210916L1-42.1).
2. Enter enable at the initial command prompt to access the Enable mode’s priviledged
commands.
3. Enter configure terminal to access the Global Configuration mode.
4. At the (config)# prompt, enter interface t1 0/x to access the interface configuration mode for
the DSX-1 interface.
5. Enter description 12 Network to PBX
to the DSX-1 interface.
6. Enter tdm-group 2
DSX-1 interface (t1 0/x).
7. Enter no shutdown to activate the interface.
8. Enter exit to return to the Global Configuration mode.

type t1-rbs supervision wink role network to create and set up this
trunk group for use with T1-RBS (DSX-1) interface.
11. Enter connect t1 0/x tdm-group 2
to allow the physical DSX-1 interface (t1 0/x) to pass the
tdm group to the end device.
12. Enter vad to enable Voice Activity Detection (VAD). VAD detects silence during a call to
reduce the bandwidth a call uses when voice packets are not being transmitting.
13. Enter end to exit the Global Configuration mode.
14. At the # prompt, enter copy running-config startup-config to save the running
configuration to the start-up configuration. The configuration must be saved to the unit’s
nonvolatile random access memory (NVRAM) to prevent the loss of configuration during a
power cycle.
