DESCRIPTION
Use these fields to specify the ISDN PRI interface which you want to configure.
Specify the X6004 for which you want to configure ISDN PRI settings. This field is
only configurable if you have more than one X6004 working in a ZyStack.
Specify which ISDN PRI interface card you want to configure. The cards are
identified by the extension card slot they are installed in. Select one of the slots or
select All to make the settings the same for all ISDN PRI interface cards.
Specify the PRI port on the ISDN PRI interface card you want to configure.
Select a switch type depending on T1 or E1 mode and the technology your
telephone company uses. You can select 4ESS, 5ESS, DMS or NI2 switch type if
you connect the port to a T1 line while you can select NET5, AUS or Q.SIG switch
type if you connect the port to a E1 line.
Select NT (Network Terminal) if a TE device (for example, an ISDN phone)
connects to the specified port. Select TE (Terminal Equipment) if this port
connects to a NT device (for example, a PBX). See
information.
Select the role of a PRI interface in an ISDN Q.SIG network (Master or Slave) and
the method to avoid channel collision (SIDE A or SIDE B).
The setting is only available for the switch type Q.SIG.
This specifies the transmission and receiving levels to cable length. Depending on
a T1 or E1 line the port is connected to, you have the following options.
T1: You can select one of the following options based on the necessary
transmission/receiving level (using CSU) or possible cable distance your
estimated between two PRI peers (using DSX).
CSU 0 = 0 dB
CSU 75 = 7.5 dB
CSU 15 = 15 dB
CSU 225 = 22.5 dB
DSX 110 = 0~110 ft.
DSX 220 = 110~220 ft.
DSX 330 = 220~330 ft.
DSX 440 = 330~440 ft.
DSX 550 = 440~550 ft.
DSX 660 = 550~660 ft.
E1: Select one of the following options based on the possible cable distance your
estimated between two PRI peers.
120 = 120 ft.
75 = 75 ft.
This is a type of framing which decides the way to align framing channels. You
have to configure same framing type in both connected PRI devices.
Depending on a T1 or E1 line the port is connected to, you have the following
options.
T1: SF (Super Frame), ESF (Extended Super Frame).
E1: CRC4 (Cyclic Redundancy Check 4), NonCRC4 (None Cyclic Redundancy
Check 4).
