Media Module Administration And Options; Error Log Entries And Test To Clear Values - Avaya G350 Maintenance Manual

Media Module Administration and Options

The DS1 configuration for each Media Module is administered on the DS1 Media Module form. Bit
Rate is set to 1.544 Mbps for 24-channel systems, and 2.048 Mbps for 32-channel systems. Country
Protocol is used to drive layer 3 protocol decisions based on PRI specifications specific to a given
country (not those related to specific features). This Country Protocol is independent of the Country
parameter administered on the country-options system-parameters form. Different MG-DS1
Media Modules may be administered with different Country Protocols, allowing the switch to act as a
gateway between two incompatible ISDN-PRI implementations (for example, between two different
countries). US systems use country protocol 1.
Echo cancellation is administered in part by administering an echo cancellation plan. Currently, DS1
Echo Cancellation Plan 4 is the default plan.
CAUTION:
The DS1 Echo Cancellation Plan 1 uses a 96ms echo tail and introduces 6db of loss for
additional cancellation. Because no digital facilities have ever introduced loss, this is an
unexpected side effect of the Plan 1 echo cancellation feature. Since services personnel
might not expect to find it there, services might try to change the loss plan to compensate,
which can lead to other problems.
