Configuring E1 lines
Setting the general parameters
To begin creating a new E1-line configuration, open the Net/E1 > Line Config menu and
display an available profile:
Net/E1
Line Config
Line Config profile
Name=
1st Line=
2nd Line=
back-to-back=
Line 1...
Line 2...
Line 3...
Set the Name parameter to assign a descriptive name to the configuration. (You can configure
multiple profiles for the same slot and activate a profile when it is needed. To activate a profile,
see “Activating a profile” on page 2-7.)
You can set 1st Line and 2nd Line to Trunk (indicating a standard E1 interface with signaling
information), Quiesced, or Disabled. For the second line connected to a MAX 6000 E1 slot,
you can also specify D&I (Drop-and-Insert) service. (A MAX 3000 unit has no D&I setting for
the 2nd Line parameter. Instead, line 3 can be used for D&I only.) Drop-and-Insert on the
second line specifies that some of the first line’s channels transparently move to the second
line. A device such as a PBX connected to the second line is not aware that the channels
actually pass through the MAX unit.
You can set the back-to-back parameter to configure DASS-2 and DPNSS lines in a
back-to-back connection. A crossover cable connects an E1 port of one MAX to an E1 port of
another MAX. No switch is required, and the connection is entirely local. One MAX should be
set up for DTE operation, and the other for DCE operation.
For more information about each parameter, see the MAX Reference.
Connecting to the Central Office switch
To configure a line’s connection to the Central Office switch, open the line’s subprofile in the
Line Config profile and set the following parameters:
For detailed information about each parameter, see the MAX Reference.
Signaling mode
You must configure the signaling type (Sig Mode) for each E1 line.
Parameter Specifies
Sig Mode The signaling type for the line.
Switch Type Type of switch (carrier specific) providing the ISDN service.
Framing Mode Physical-layer frame format of the E1 line.
