Specifying the other required parameters
In addition to setting signaling mode, you must perform the following steps for the profile:
1
Set the Framing Mode parameter to D4 or ESF to specify the type of framing the line uses.
2
Set the Encoding parameter to None (identical to AMI, but without density enforcement),
AMI, or B8ZS to specify the encoding used on this line.
3
Set the FDL parameter to N/A (appropriate for Framing Mode=D4), None, AT&T, ANSI,
or Sprint to specify the Facility Data Link (FDL) used on the line.
4
Set the Length parameter as appropriate for your site. If you are using the internal CSU,
keep it at the default value.
5
Set the Front End parameter to CSU to enable the internal CSU. Disable the internal CSU
by setting Front End to DSX.
6
Set the Buildout parameter to specify proper line attenuation. Obtain this information from
your service provider. The default is 0dB.
7
If you cannot accept the default channel usage of switched for every channel on the line,
set the Ch N parameter to Switched (the default), Nailed (dedicated), or Unused (not in
service).
Note:
To test the line later, you must have at least two switched channels. If you plan to
use a channel for drop-and-insert (D&I), you can enter it as Switched for the Quickstart
and then change it to D&I for the final installation.
Routing incoming calls
No configuration is required to route ISDN calls. The signaling information carried by the
D channel defines whether the call goes to a digital modem or to an Ethernet bridge or router.
If you are using inband signaling, configure incoming call routing for the T1 line by setting the
Ch N # and Ch N Slot parameters as follows:
1
For the Ch N # parameter, enter the unique digits of the telephone number used to reach
channel N.
For example, if your line is set up as illustrated in Table 6-3 on page 6-11, enter 1111 for
the first 12 channels, and 2222 for the last 12 channels.
2
For each T1 channel that answers analog calls, set the Ch N Slot parameters to the number
of the slot that contains the modem card.
For example, if the modem card is in slot 7, set Ch 1 Slot to 7, Ch 2 Slot to 7, and so on, up
to the total number of analog calls you want the MAX to accept on this T1 line. These
settings tell the MAX to route incoming analog calls to the digital modem card.
3
For each T1 channel that answers digital calls, set the Ch N Slot parameters to 4, the
default number of the slot that contains the MAX unit’s Ethernet module. These settings
tell the MAX to route incoming digital calls to the Ethernet module to be bridged or routed
to their destination.
