Reference Guide for the Model XM128 ISDN Digital Modem

Bearer capability and low-layer compatibility information elements are determined when you configure the B channel protocols using the ATBnn command. The outgoing low-layer compatibility information element can be turned on or off by setting the S80 bit n as follows:

n = 4 for analog adapter 2

n = 6 for ISDN data calls

n = 7 for the analog adapter 1

Table 7-2 lists the commands for enabling and disabling outgoing low-layer compatibility.

Control of ISDN Phone Numbers and Subaddresses

The calling-party number information element identifies the origin of a call, and the called-party number information element identifies the destination of a call.

The calling-party subaddress information element identifies the subaddress associated with the origin of a call.

The called-party subaddress information element identifies the subaddress of the destination of a call.

Each type of outgoing call can be assigned with one number/subaddress pair by using the AT&ZOx=s command. The possible values for x are as follows:

x = I for ISDN data calls

x = A for the analog adapter 1

x = B for the analog adapter 2
