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*
.
●
The called address field in the template record 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??
.
●
The called address field in the template record 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
.
