Procedure for DAC GE Configuration
Figure 7-17 shows a typical configuration screen, which provides a view/change
capability for operational mode, channel type, channel capacities, transport
channel encoding, and Ethernet port settings.
Option tabs provide access to Priority Mapping and VLAN Tagging screens.
When you have completed the required configuration steps, go to the Circuits
screen to configure circuit cross-connects. Refer to Procedure for Configuring
Circuits - Traffic on page 9-9, Volume IV, Chapter 9.
To configure the DAC GE :
1. From the Plug-ins screen, select the required module.
2.
Capacity Type.
DAC GE supports selection of E1 / 2.048 Mbps, DS1 / 1.544
Mbps or STM1/OC3 / 155 Mbps. If the required capacity type selection is
red-flagged the backplane bus must be reset: go to

and reset the Bus Configuration accordingly.
Ethernet data is mapped into the same byte-wide frames used to transport
TDM data, it is not transported over TDM. 9500 MXC incorporates a
universal modem design that does not distinguish between the type of data to
be transported, Ethernet or TDM, with the result that when 9500 MXC is
configured for Ethernet data, or Ethernet and TDM data, the full configured
capacity is available for user throughput.
3.
Channel C1 and Channel C2 Capacity
: Select the capacity required per
channel. Channel capacity can be direct-entered as NxE1 / 2.048 Mbps,
NxDS1 / 1.544 Mbps, or NxSTM1 / 155 Mbps where the maximums for one
channel or the total for both channels are:
• 100xE1 in 1xE1 / 2.048 Mbps steps
• 127xDS1 in 1xDS1 / 1.544 Mbps steps
• 2xSTM1 in 1xSTM1 / 155 Mbps steps
These maximum capacities also represent the backplane bus maximums.
4
For channel capacity selections above 10xE1 / 20 Mbps or 16xDS1 / 24
Mbps, a license upgrade will be required for the associated RAC.
Channel capacity is mapped to a RAC (radio) or to a DAC 155oM (fiber).
• RAC 30 and RAC 40 support link capacities to 153 Mbps (Nx 2 Mbps) or to
154 Mbps (Nx 1.5 Mbps).
• RAC 3X supports link capacities to 204 Mbps (Nx 2 Mbps), 154 Mbps
(Nx 1.5 Mbps), or 310 Mbps (Nx 155 Mbps).

Except for a DS1 selection where the backplane bus max is 128xDS1.
