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.
Tab. 2.40: Example of an LCR table with a PISN-internal entry
• The external phone number 0-624 38 27 will be routed in accordance with the
subscriber configuration (no LCR routing as there is no E entry for digit
sequence 62).
• The PISN phone number 62 2020 will be routed via the routing table "Region
62".
Emergency Routing (X Prefix)
If specific phone numbers (e.g. emergency numbers) are to be routed in each and
every case (including forced routing) in accordance with the subscriber configura-
tion or subscriber selection and not according to LCR criteria, they must be
entered with the prefix "X" in the LCR table. In the "Routing Table" column the
system enters the term "Emergency" and a routing table is not allocated.
