Description
• DAC 155oM multiplexes one STM1/OC3 tributary to/from a 9500 MXC
backplane configured for NxE1 or DS1, to support concurrent SDH and
PDH tributary access.
• DAC 2x155e supports two STM1 electrical tributaries.
• DAC ES supports four 10/100Base-T Ethernet ports over one or two radio
and/or fiber NxE1/DS1 transport channels
• DAC GE supports.three 10/100/1000Base-T electrical ports and one
1000Base-LX optical port, over one or two transport channels.Channels are
configured for Nx2 Mbps, Nx1.5 Mbps, or Nx150 Mbps capacities.
AUX provides synchronous and asynchronous auxiliary data channels, NMS
porting, and alarm inputs and outputs. Sync data at 64 kbps and async to 19.2
kbps.
NPC provides redundancy for the NCC TDM bus management and power
supply functions.
A minimum configured 9500 MXC Node would typically consist of an ODU, and
an INU populated with an NCC, FAN, RAC, and DAC.
