Switch Type Setup for North America
In North America, the popular types of switches are AT&T 5ESS, Northern Telecom DMS100,
and Siemens EWSD. All of these switches run software that either conforms to the National
ISDN-1 standard or a custom version. The Model XM128 modem supports the six different
combinations listed in
Table 4-4 . The value for n in the ATPn command is shown in the AT
command column. The ATPn command programs the D channel protocol so that the Model
XM128 modem works with the type of switch that is connected to your ISDN line.
To set your switch type, use AT commands (examples given are if your switch type is DMS 100
with Custom Protocol) and follow these steps:
1. Type ATP0 and press [Enter].
You should receive the following response:
OK
Switch Type: Northern Telecom DMS 100
2. Type AT&WZ and [Enter] to save the settings.
You should receive the following response:
OK
