Note This option is available for E1 PRI and T1 PRI connection types. The option is not available for T1 CAS connection types.
|
Delay for First Restart (Ticks)
|
Enter the rate at which the spans are brought in service. The delay occurs when many PRI spans are enabled on a system and the Inhibit Restarts at PRI Initialization check box is unchecked.
For example, set the first five cards to 0 and set the next five cards to 16. (Wait 2 seconds before bringing them in service.)
Note This option is available for E1 PRI and T1 PRI connection types. The option is not available for T1 CAS connection types.

|
Inhibit Restarts at PRI Initialization
|
This setting allows you to change the amplitude of the voice signal coming into the gateway created by adjusting the decibel level of the signal. You can increase the volume of a signal coming into the gateway by either increasing input gain or decreasing attenuation. You can decrease the volume of the incoming signal by either decreasing the input gain value or increasing the output attenuation.
The minimum value is -6, and the maximum value is 14.
Note This option is available for E1 PRI and T1 PRI connection types. The option is not available for T1 CAS connection types.
|
Enable G. Clear
|
Check this check box to enable G. Clear Codec support. Checking this check box causes echo cancellation and zero suppression for outbound calls to be disabled.
Note This option is available for E1 PRI and T1 PRI connection types. The option is not available for T1 CAS connection types.
|
Transmit UTF-8 for Calling Party Name
|
If you check the Transmit UTF-8 for Calling Party Name check box, the gateway sends unicode for the calling party name.
Note This option is available for E1 PRI and T1 PRI connection types. The option is not available for T1 CAS connection types.

|
Check the check box to enable delivery of the display information element (IE) in SETUP and NOTIFY messages (for DMS protocol) for the calling and connected party name delivery service.
|
Redirecting Number IE Delivery-Inbound
|
Check this check box to indicate the first redirecting number and the redirecting reason of the call when the call is forwarded. (The UUIE part of the outgoing SETUP message from the Cisco Unified Communications Manager Business Edition 3000 includes the Redirecting Number IE.)
Uncheck the check box to exclude the first redirecting number and the redirecting reason.
You use Redirecting Number IE for voice-messaging integration only. If your configured voice-messaging system supports Redirecting Number IE, check the check box.
|
Redirecting Number IE Delivery-Outbound
|
Check this check box to accept the Redirecting Number IE in the incoming SETUP message to the Cisco Unified Communications Manager Business Edition 3000. (The UUIE part of the SETUP message includes the Redirecting Number IE.)
Uncheck the check box to exclude the Redirecting Number IE.
You use Redirecting Number IE for voice-messaging integration only. If your configured voice-messaging system supports Redirecting Number IE, you should check the check box.
|
Setup non-ISDN Progress Indicator IE Enable
|
Check this check box only if users are not receiving ringback tones on outbound calls.
When this check box is checked, the Cisco Unified Communications Manager Business Edition 3000 sends Q.931 Setup messages out digital (that is, non-H.323) gateways with the Progress Indicator field set to non-ISDN.
This message notifies the destination device that the gateway is non-ISDN and that the destination device should play in-band ringback.
This problem usually associates with a Cisco Unified Communications Manager Business Edition 3000 that connect to PBXs through digital gateways.

Called Party IE Type Unknown
|
Select the format for the number type in called party directory numbers.
Cisco Unified Communications Manager Business Edition 3000 sets the called directory number (DN) type. Cisco recommends that you do not change the default value unless you have advanced experience with dialing plans such as NANP or the European dialing plan. You may need to change the default in Europe because Cisco Unified Communications Manager Business Edition 3000 does not recognize European national dialing patterns. You can also change this setting when you are connecting to a PBX that expects the called directory number to be encoded to a non-national type numbering plan.
Select one of the following options:
•Cisco Unified Communications Manager—Use when the Cisco Unified Communications Manager Business Edition 3000 sets the directory number type.
•Unknown—Use when the dialing plan is unknown.
•National—Use when you are dialing within the dialing plan for your country.

Input Gain (dB)
Note For T1 CAS, this option is in Product Specific Configuration Layout section.
|
This allows you to change the amplitude of the voice signal coming into the gateway created by adjusting the decibel (dB) level of the signal. You can increase the volume of a signal coming into the gateway by either increasing input gain or decreasing attenuation. You can decrease the volume of the incoming signal by either decreasing the input gain value or increasing the output attenuation.
The minimum value is -6, and the maximum value is 14.
|
Output Attenuation (dB)
Note For T1 CAS, this option is in Product Specific Configuration Layout section.
|
Attenuation is measured in decibels, and the lower the number, the better the voice quality. Adjust the attenuation and input gain values to achieve maximum voice quality.
The minimum value is -6, and the maximum value is 14.
|
Output Level (dB)
Note This option is available only for T1 PRI and T1 CAS connections.
|
This option sets the attenuation of the signal before it enters the line. To reduce the line loss set the output level to 0, -7.5, or -15 dB.
