Protocol Specific Configuration

 

Terminal-Definition

mux:port:subc

The port assigned must be configured as above and the ACC

 

card must have the appropriate HDLC/LAP-D firmware

 

configured. You must also have defined the subchannel number

 

in the Subchannel definition section.

dtype

The device type of the HDLC/LAP-D terminal must be

 

LAPD.DLE.

poll/select

This supplies the “POLL” and “SELECT” parameters

 

for the ZCOM Terminal-Definition. These are used to

 

specify:

 

• whether the HDLC/LAP-D terminal acts as a DTE

 

(user side) or DCE (network side),

 

• the frame re-transmission time-out value,

 

• the re-transmission count limit,

 

• the outstanding frame window size to be used, and

 

• the maximum frame size allowed.

 

In most cases a pre-configured keyword will suffice. For

 

the list of currently predefined keywords, see

 

“Predefined Configuration Values” section of this

 

chapter. If a different set of values is required, then

 

different values for the “POLL” and “SELECT” codes

 

may be entered here in the standard poll and select

 

format in hexadecimal. For the format of these words,

 

see “Poll/Select/Option Configuration Values” on page
