If you are replacing called or calling address with original user data,
all the replacing characters must be digits. Also, the user data must be
specified in the template ID.
T

Translation Examples
Example 1 – Replacing the first four digits of the called address with digits from the
user data field:
Assume the Template ID is
3110*U*
and the called address field in the template is
U1234X5
. A packet with called address
31101234567890
and user data
5678
is
received. The packet matches Template ID
3110*U*
; therefore, a translation
occurs as follows:
◆
U1234
of
U1234X5
indicates that positions 1, 2, 3, and 4 of the user data of
the received packet (
5678
) will replace the first four digits of the called
address (
3110
).
◆
X5
of
U1234X5
takes the fifth position of the template (
*
) and searches for a
match in the part of the original called address not yet translated
(
1234567890
). (The match is found in the entire string
1234567890
.)
The translated called address is
56781234567890
.
Example 2 – Appending the subaddress from the user data to the called address:
Assume the Template ID is
3110*U??
and the called address field in the template
is
X12345U12
. A packet with called address
311012345678
and user data
99
is
received. The packet matches Template ID
3110*U??
; therefore, a translation
occurs as follows:
◆
User data
99
from the packet is appended to the called address
311012345678
.
The translated called address is
31101234567899
.
