paging. It works only with SL CPU.
16
Subscriber Line Cards
• There are 2 variants in line cards –
a.
LCS 1
b.
LCS 3
• LCS 1 is having normal extension functionality
with CLI + Msg Waiting Lamp.
• LCS 3 = LCS 2 + Reversal extending
• Msg waiting Lamp / Line reversal extending, is
available only with SL CPU.
17
Subscriber Line Cards
