7-4 117021-A Rev. A
Select NONPRI to indicate that all the lines have a permanent circuit number
and are for leased lines, Frame Relay, or permanent connections for other
non-ISDN PRI applications.
Select PRI to indicate that the lines are for switched circuits using ISDN.
3. Click on OK.
The Edit Clock Parameters parameters window appears. Continue with the
next section, “Setting the Clock Parameters.”
Setting the Clock Parameters
Clock parameters define the timing sources that apply to ports and DS0 timeslots
that a MCE1 or MCT1 link or net module supports.
To set the clock parameters:
1. Display the Edit Clock Parameters window.
You access the window based on which link or net module you are
configuring, and whether or not you’ve previously configured the port:
• Newly-installed Single- or Dual-Port MCE1 or MCT1 link module
The Edit DS1E1 Clock Parameters window appears automatically the first
time you configure an interface.
Note: The 120-ohm MCE1-II link module supports ISDN PRI.
MCE1 net modules support only non-PRI applications. If you try to configure
an ASN MCE1 port for PRI, Site Manager displays a warning to indicate that
this version of MCE1 does not support ISDN.
Site Manager: Port Application Mode parameter: page A-22 (MCE1)
Site Manager: Port Application Mode parameter: page A-26 (MCT1)
Note: DMCE1 and DMCT1 link modules contain a single clock chip that
provides the timing signals for both ports. Therefore, clock parameters that
you set for the first port apply to the second port on the module.
Timing is independent for the two ports on a DMCT1 net module, and for the
four ports on a QMCT1 and QMCT1 w/ DS0A link module. For these
modules, you select the timing source for each port.
