assigned.
assigned.
2.
Even when LCRS is assigned, digit outpulsing to the distant office is not started until all digits have been
received when the signaling is MF. If there is DP or PB lines among alternate routes, an outgoing call may
be originated by seizing a DP or PB line, even when the route advance sequence for that line is lower than
MF lines. When the route advance sequence of MF to DP or PB is predetermined, LCR must be assigned
in the numbering plan.
