On 2-port or 8-port cards, the port must be defined as operating
in SDLC mode. The ACC cards may use either an external (modem supplied) clock,
or an internal (card supplied) clock. With an external (modem supplied)
clock, the speed is for documentation purposes only, and will not
be used by the ZCOM system.
The clock multiplier should be x1, and the encoding mode would normally
be NRZ (although NRZI may be used).
A sample Port-Definition is as follows:
Port 01:04 RS232 57600 Ext SDLC x1 NRZ
For the E1/T1 ACC card there are no Port-Definition requirements specific
to the HDLC/LAP-B (ABM) protocol. A typical E1/T1 Port-Definition
would be:
Port 0:2 E1RJ45 Ext CRCMF HDB3
Refer to the section on the TTGEN utility in the ACC
Utilities Reference Guide for more information on specifying
the port and subchannel parameters.
