programmed. If you do not see any response from the device, go over your installation
procedures again or contact the ZyXEL Technical Support.
Configuring Your ISDN Switch Type
In North America there are three popular types of switches, they are:
T
AT&T 5ESS
T
Northern Telecom DMS100
T
Siemens EWSD
These switches are either running software that conforms to the National ISDN-1
standard, or a custom version. Currently, the Omni TA128 supports a total of 6 different
combinations, listed in the following table.
You must have the switch type information available when you install your ISDN line.
This information must be obtained through your local telephone company.
See Chapter Two - "Ordering an ISDN Line" for details.
The ATPn command is used to program the D channel protocol. This is to allow the
Omni TA128 to work with the type of switch your ISDN line is connected to. "n" is a
digit that indicates the type of switch. Please use the following table for the "n" value.
Note: The Omni TA128 is shipped with a default value of ATP0, which is Northern
Telecom's DMS-100 switch with Custom protocol.

company, enter the proper value.
