3300 ICP Technician’s Handbook
Notes:
1 All 3300 systems can support a maximum of 64 members in a group page.
However, the MXe Standard with 64 E2T channels should restrict the number
of members in a group page to less than 32 to reduce the risk of conflict with
trunk E2T channels.
2. In these configurations there are always more E2T sessions available than
can be used by the T1/E1 trunks, and the full balance of 64 can be used in a
group page with no restrictions.
3. The 192 Gateway is not defined in any software setup procedures, but is a
special case of the resource allocations based on the specific hardware
modules installed.
4. When the system boots up, if it detects either of the following hardware
configurations, the number of voice mail ports will be automatically reset to
zero:
- two DSP II modules and one VEC module, or
- one DSP II module and four dual T1/E1 framers
5. The MXe Controller has been shipped in three different versions since it was
introduced. The original version has four AD21262 DSP devices on the main
board; the later versions (MXe II and MXe III) have four AD21363 DSP
devices. The MXe II and MXe III can be configured as a 192 channel TDM
gateway, as shown in this table. Although not shown in this table, it is possible
to upgrade the original MXe to a 192 Gateway, but with some limitations since
it does not have as much DSP resources available. The original MXe can only
be used as a 192 Gateway when a second VEC module is installed. The two
options shown for the 192 channel TDM gateway that do not have the second
VEC cannot be used, because they will not have enough DSP resources to
function properly.
