Modular ICS 7.1 Installer Guide
Framing
Framing allows you to select the framing format used by your
T1 or PRI service provider.
Press
CHANGE
to select the setting:
ESF
(Extended Superframe)
or
SF
(Superframe).
Tips -
The ISD/TT setting is only for T1 and PRI
interfaces (MCI services only). ISD/TT provides a loss level
that is similar to DAL except for certain analog connections
where the DB level increases by three.
Each loss plan uses a transmit objective loudness rating of -
46 dB. The ISDN and ISD/TT loss plan uses a receive
objective loudness rating (ROLR) of 51dB and the PSTN loss
plan uses a ROLR of 48 dB.
Choosing the wrong setting may affect voice quality.
You must disable the Trunk Cartridge using
Module status
in
Maintenance
before you
can change this setting. See Module status on
page 537 for details.
Tips -
This setting only appears for DTIs. Consult your T1
or PRI service provider for the proper setting.
SF or Superframe is sometimes known as D4.
