Enable On-Module Dialing
In previous versions of the Mitel 5000 there was a system level flag labeled Enable T1/E1/PRI
Dialing. This flag has been removed and replaced with this port level flag for the T1M and T1M-
2 modules. This flag handles pulse and DTMF dialing for T1M/T1M-2 ports. It is set to Yes by
default.
To change the Enable On-Module Dialing setting:
1. Select the current Value and then place a check mark in the box by selecting it. To
remove the check, select the box again.
2. Press ENTER or select another field to save the change.
Framing Type
The type of framing scheme used by the T1/E1 trunks connected to the module can be as
follows:
• T1 Trunks: D4 Superframe or Extended Superframe (ESF)
• E1 Trunks: Common Channel Signaling or Channel Associated Signaling
To set the framing type:
1. Select the current Value, then use the drop-down list box to scroll to the desired setting.
2. Press ENTER or click another field to save the change.
Zero Code Suppression
The trunk zero-suppression scheme supports the followings:
• T1/PRI and T1/E1/PRI modules: AMI (Bit 7), Bipolar Eight Zero Substitution (B8ZS), or
None
• E1/PRI modules: HDB3 or None
To change the setting:
1. Select the current Value, then use the drop-down list box to scroll to the desired setting.
2. Press ENTER or click another field to save the change.
Line Impedance
(Applies only to E1/PRI-equipped modules.) Set this value to the line impedance the CO is
using for E1/PRI. The value here must match the CO setting. The system supports the following
line impedances:
• 120 ohms (default)
• 75 ohms
IMPORTANT
DB Programming displays an error message under the following
circumstances:
• Change the port type of one port if the other port is programmed (not
None).
• Change the Framing Type under a T1 port and the other port is
programmed (not None). This field also exists under the T1/PRI port
type, but it is OLM only.
DB Programming displays: WARNING: Changes to this field are only
recommended on an idle system as this may cause a short pause in audio
on the other port of this module (but no dropped calls). Would you like to
continue?
