Link Configuration: LAPBMUX Link Data
Fields Physical path
The physical path of the LAPBMUX (Sync MUX) card.
The basic formula for deriving the physical path is:
A Class PathNumber /1. card port number
N Class PathNumber /0/1. card port number
where (a) PathNumber is a number corresponding to
the card cage the MUX card is in:
Card cage 0: PathNumber = 0/2
Card cage 1: PathNumber = 0/6
(b) / is the slash character (not the division sign), (c)
portnum is the card portnumber used, it’s value is from
0 to 7.
Examples:
A Class — PathNumber /1. port num
If the MUX card is in slot 0/6/2 and if using card port
number 4, then the physical path is: 0/6/2/1.4
N Class — PathNumber /0/1. port num
If the MUX card is in slot 0/6 and using card port
number 2, then the physical path is: 0/6/0/1.2
A valid hardware path should confirm the following:
1. Path is non-empty and fits the field (<= 32 chars).
2. Path begins and ends with a digit.
3. Path contains only digits, “/”, or “.” characters.
4. Path contains no occurrences of “//”, “..”, “./”, “/.”
5. Other than that, ANY other combination of
characters should be accepted, out to the full 32
characters.
Modem Type
V.25bis is a ITU-T specification for a modem command
language and overall modem behavior. It includes both
asynchronous and synchronous command interfaces.
Hayes is the dialing standard for async modems. Hayes
includes V.25bis in its ULTRA modems to support
synchronous out-dial facilities of host computers and to
support the evolution of synchronous communications
software on PCs.
