Port-Definition
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

parameters.
