Part 2 Call Routing 309
The first digits of an external phone number can be evaluated in terms of the LCR
function if they are entered in the LCR table (evaluatable digit sequence) and allo-
cated to a routing table (2nd column). Up to 400 digit sequences can be entered
in total in the LCR table.
An analysable digit sequence can consist of up to 10 digits.
Tab. 2.41: Example of an LCR table
Based on the entries in this LCR table, calls are routed as follows:
• In this example phone number 0-061 601 22 22 is routed via the "National"
routing table.
• Phone number 0-0033 1 41 23 45 67 is routed via the "International" routing
table.
• Phone number 0-032 631 27 17 is routed in accordance with the subscriber
configuration (no LCR routing as a routing table was not specified for digit
sequence 032).
• Phone number 0-0044 1425 275341 is routed via the "United Kingdom" rout-
ing table.
• Phone number 0-0044 171 938 9123 is routed via the "London South West"
routing table.
• Phone number 0-631 27 17 is routed in accordance with the subscriber config-
uration (no LCR routing as the phone number does not contain any analysable
digit sequences).
External and PISN-Internal Entries (E and I Prefix)
To indicate whether an entry in the LCR table relates to an external destination in
the public network or to a destination in the private leased-line network, the pre-
fix "E" (for external) or "I" (for PISN-internal) must be added to the digit
sequence.
