ISDN Port Configuration 279
Mode
Port ISDN
Command Purpose
Step 1 node (prt-isdn)[ slot/port ]#l2proto
pmp
or
node (prt-isdn)[ slot/port ]#l2proto
pp
Specify the ISDN layer 2 protocol
Make sure the connected ISDN device operates
the same layer 2 protocol!
28.7 Configure PRI Port Parameters
Of the 32 time slots in an ISDN PRI, slot 0 is reserved for synchronization, slot 16 is used for
signaling, and the remaining 30 slots can be used as B-channels for dial-up circuits. SmartWare offers
various options to specify the use of these channels.
Procedure
To configure PRI port parameters
Mode
Port ISDN
Command Purpose
Step 1 node (prt-isdn)[ slot/port ]#clock-
mode master
or
node (prt-isdn)[ slot/port ]#clock-
mode slave
Specify PRI clock mode
The E1 interface can either generate the clocking
for the line, or accept the clock from the line.
The options ‘master’ or ’slave’ determine the
clocking method:
Master: Generates clock
Slave: Accepts clock (Default)
Step 2 node (prt-isdn)[ slot/port ]#channel-
range min max
Specify channel range to be used
Limits the time-slots to be used for calls to the
range between
min and max . This is in some
cases required for interoperability with ISDN
services that impose the same limitations.
Call slots outside the defined range are rejected
(busy line). If no range is defined (Default) all 30
time slots are available for use.
Step 3 node (prt-isdn)[ slot/port ]#max-
channels number
Limits the total number of concurrent calls on
the PRI port.
Note: if the channel-range and max-channel
command are used simultaneously the lower
number of channel is the limiting parameter.
