DSS1 protocol parameters
Reverse mode NT/TE
– this option refers to L3 signalling only. Check this
option to make a TE port behave as an NT port (and vice versa).
Do not send time at NT
– use this option to disable sending of the connection
date and time information within the CONNECT message from an NT port to a TE
port. Available for NT ports only.
Ignore unset explicit channel
– use this option to enable call establishment
without an explicitly set B–channel.
Always select B–channel
– use this option to disable sending the Channel
identification information within the SETUP message with channel signalling.
Available for TE ports only.
Disconnect L2 if no call
– use to disconnect the L2 layer on an inactive
interface. The PBX automatically disconnects the layer after a
. An
timeout
incoming call automatically reconnects the layer.
Keep L2 connected
– check this option to make the PBX keep the L2 layer
connected on this interface without any incoming call. This option may not be
combined with the
option.
Disconnect L2 if no call
Disconnected L2 as error
– use this option to activate a caution about the
second layer being disconnected. This fact is indicated by a red exclamation mark
on the port in the
menu and a red text in the upper stack
Hardware – Boards
status field. This option may not be combined with the
Disconnect L2 if no call
option.
Terminals
– not applied for PRI ports.
is able to process (i.e. resend to an interface other than
2N NetStar
®
ISDN) only
G.711 A-law
encoded calls on the ISDN interface. Calls
encoded by
G.711 µ-law
can only be resent between the ISDN
interfaces in the PBX.
Digital interface diagnostic
Line state
– the parameter cannot be set. It only shows the state of the first
interface layer.
Number of SLIPs per minute
– this parameter gives the count of slips. A slip is
caused by different clocks of the PBX and the active terminal. This value is
updated every 6 seconds and represents a weighted average per minute.
Bit error rate per second
– the BER parameter gives a count of incorrectly
transferred bits during transmission. The value is updated every 6 seconds and
represents a weighted average per minute.
If the
port supervision is used, enable some or all of the following parameters:
SNMP
,
,
,
Inactive L1 as error Disconnected L2 as error Nonsynchronous L1 as error
. If not, the port error will not be detected and the PBX will be unable to
BER as error
send a warning.
