LCR with Key Telephones

LCR routing when dialling via the line keys depends on the "Force route" author-
ization.
• "Force route" enabled:
Routing is effected via the KT route as with a deactivated LCR function.
• "Force route" not enabled:
Routing is effected via the LCR function.
5.4.8

LCR in the private Leased-line Network

Where the LCR function is concerned, a private leased-line network (PISN) is a spe-
cial network provider, characterized as follows:
• A PISN is usually reached directly (see "Direct Network Access", Page 2.155).
• Digit sequences of PISN-internal phone numbers must be entered with the I-
prefix in the LCR table (see "External and PISN-Internal Entries (E and I Prefix)",
Page 2.160).
• Overflow routing from the PISN to the public network is implemented with the
LCR function by entering the PISN as the primary network provider and the
public network provider as the alternative network provider. Unlike fallback
routing, routing to the alternative network provider does not generate an
event message (see also the about alternative routing on Page 2.164).
