6. 6. 7 LCR with Key Telephones
LCR routing when dialling via the line keys depends on the Force route authoriza-
tion.
• 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.
6. 6. 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 223).
• 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 228 )
• 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 pub-
lic network provider as the alternative network provider. Unlike fallback routing,
routing to the alternative network provider does not generate an event message
(see also "Alternative Routing (Fallback Routing)", page 232).
Aastra Intelligent Net:
In an AIN the master’s LCR configuration always applies to all the
nodes. The LCR configuration of a satellite is effective in the offline
mode only (i. e. when the connection to the master is interrupted).
