Messaging Telephone Number Format

The Messaging Telephone Number is a structure which contains the information needed by the Modem
module to send a message. The Messaging Telephone Number is an ASCII string with a leading length
byte followed by ASCII characters. The maximum length of a Messaging Telephone Number is 120 bytes
(which includes the length byte).
The Messaging Telephone Number contains up to 6 fields separated by a forward slash (/) character.
Back-to-back slashes indicate an empty (null) field. Null fields are set to default values in the Modem
module.
Format: <Telephone Number>/<ID>/<Password/<Protocol>/<Standard>/<Format>
The Telephone Number field is the telephone number that the Modem module dials when sending a
message. If the message being sent is a text or SMS message, this is the telephone number of the
service provider. If the message is a numeric page, this field is the pager telephone number. If the
message is a CPU data transfer, this is the telephone number of the remote device. The maximum
number of characters in this field is 40.
The ID is the pager number or cellular telephone number. This field should consist of the digits 0 to 9 only.
If the protocol is a CPU data transfer, this field is used to supply the address of the remote device. Up to
20 characters are allowed in this field.
The Password field is used to supply the a password for messages sent via TAP if a password is required
by the service provider. For messages sent via UCP this field is used as the originating address or
telephone number. If the message is a CPU data transfer to another Modem module, this field can be
used to supply the password of the remote Modem module. The password can be up to 15 characters in
length.
The Protocol field consists of one ASCII character which tells the Modem module how it should format and
transmit the message. The following values are allowed:
10
The Standard field forces the Modem module to use a specific modem standard. The standard field is one
ASCII character. The following values are allowed:
The Format field is three ASCII characters which specify the number of data bits and parity to be used
when transmitting the message. This field does not apply if the protocol is set to numeric paging. Only the
following two settings are allowed:
308
1 – Numeric paging protocol (default)
2 – TAP
3 – UCP command 1
4 – UCP command 30
5 – UCP command 51
6 – CPU data transfer
1 – Bell 103
2 – Bell 212
3 – V.21
4 – V.22
5 – V.22 bit
6 – V.23c
7 – V.32
8 – V.32 bit
9 – V.34 (default)
8N1 – 8 data bits, no parity, one stop bit (default)
7E1 – 7 data bits, even parity, one stop bit
