2. Synchronous lines (BSC, SDLC)
50, 100, 134.5, 200, 300, 600, 1200, 2400, and 4800 bps.
3745 Mode
Speed Selection : By SSP at generation time
NCP Parameters : CLOCKING=DIRECT, SPEED=xxx
Speeds:
1. Asynchronous lines (Start-Stop)
50, 75, 100, 110, 134.5, 200, 300, 600, 1200, 2400, 4800, 9600, and 19 200
bps.
2. Synchronous lines (BSC, SDLC)
50, 75, 100, 110, 134.5, 200, 300, 600, 1200, 2400, 4800, 9600, 19 200, 38
400, and 55 855 bps. With SDLC only, 245 760 bps is also allowed.
EXTERNAL Mode
The EXTERNAL clocking mode does not activate the ICF since the DCE provides
the transmit and receive clocks to both the LIC and itself (LIC5s and LIC6s provide
the clocking to their own LIC and are seen as "External" by NCP).
Speed Selection : By SSP at generation time
NCP Parameters : CLOCKING=EXT, SPEED=xxx
Speeds:
1. Asynchronous lines (Start-Stop):
Up to 19 200 bps.
2. Synchronous lines (BSC, SDLC):
Up to 256 000 bps.
