Firmware download
The firmware download feature makes it possible to download an image from a
remote or local source into the system running Communication Manager, and use
that image to reprogram the application code of a port circuit pack. This feature
makes updating firmware more cost effective. It also reduces the expense of
servicing the system’s port circuit packs because it eliminates the need for a
technician to be involved when a board is updated. Firmware download is
achieved using the TN799C C-LAN interface.
NOTE:
Circuit packs that can be updated with the firmware download feature have a
“P” at the end of their TN number.
Five EPN maximum in MCC1 Media
Gateways
NOTE:
This feature is for MCC1 Media Gateways when used with an S8700 Media
Server or DEFINITY® Server R configurations only.
This optional software feature allows customers that require high calling traffic
capacities to have from two to five expansion port networks (EPN) in a single
MCC1 Media Gateway. Only two port networks (PN) are generally available
unless a specialized cable was purchased from Avaya and work-arounds were
performed in software administration to make additional carriers function as
EPNs.
When this feature is activated, Communication Manager enables administration
of up to five carriers as EPNs and no custom cables are necessary. This means that
the full bandwidth of the TDM bus is available to each carrier while still enabling
the customer to have the footprint of an MCC1 Media Gateway. This is especially
appealing to call centers without IPSI/PNC duplication, where systems can be
quite large and heavily utilized.
The hardware limitation of the MCC1 Media Gateway is five port carriers. All
five can be expansion port carriers, although traffic considerations may dictate
some number less than that which is optimum. For example, a customer may
choose to have three EPN carriers and two standard port carriers.
