Reference Guide for the Model XM128 ISDN Digital Modem

7-10 Advanced ISDN

Data Call Indication

Data calls are accepted by the Model XM128 modem in the same way as with any terminal

adapter. When alerting, the Model XM128 modem sends the first Ring message to the DTE with a

format as follows:

RING <CR><LF>

[FM:[[Prefix]Calling-Party-Number][/Subaddress/]]

[TO:[Called-Party-Number][/Subaddress/]] <CR><LF>

RING <CR><LF>

The display of address information between the first Ring and the second Ring is disabled by

setting ATS84.4=1. The term Prefix is a predefined number string is added in front of the

calling-party number before indicating it to the DTE. Adding Prefix is useful for some automatic

dial-back-up systems. The number string is assigned as follows:

• ATCI<Prefix>

When and only when the type of number denotes an international number, this "Prefix" is

added to the calling-party number before indicating it to the DTE.

• ATCI<>

This command disables the international number prefix-adding function. (Default)

• ATCN<Prefix>

When and only when the type of number denotes a national number, this "Prefix" is added

to the calling-party number before indicating it to the DTE.

• ATCN<>

This command disables the national number prefix-adding function. (Default)

Disable Inbound Call Connection

In some cases, the user may require that the Model XM128 modem not answer any incoming calls.

This response is accomplished by setting the bit 0 of S-register S118 as follows:

• S118.0=0 to enable answering a call (by default)

• S118.0=1 to disable answering any call

Note:

The angle brackets (<) and (>) are part of this command.

1 2 ... 73 74 75 76 77 78 79 80 81 82 83 ... 155 156
