The CFMMR-44xx Carrier Ethernet module is equipped with four electrical Ethernet interfaces, which comply with the relevant clauses of IEEE 802.3. The four electrical Ethernet interfaces supports the following capabilities:
- 1000Base-T (1000 Mbps)
- 100Base-TX (100 Mbps)
- 10Base-T (10 Mbps)
- Full-Duplex
- Half-Duplex
- Flow Control
- Auto-Negotiation
- The four ports are equivalent and may be used interchangeably. These ports support incoming and outgoing Synchronous Ethernet operation.
System Interfaces
The CFMMR-44xx Carrier Ethernet Master IO module integrates with the rest of the MMR IDU by supporting the following required interfaces via a PCI backplane connector:
- JTAG interface from controller card (FPGA programming interface).
- I2C interface from controller card with serial EEPROM and temperature measurement device attached.
- Power disable control from controller card.
- Status/Fault indication from controller card.
- Card present indication to controller card.
- Board shall accept 5V and 3.3V power and ground with hot swap control.
- Expansion IO interface with nine LVDS pairs and nine single-ended TTL lines.
- Modem interfaces with LVDS and single-ended TTL lines.
- ROH and NMS interfaces to/from the controller card.
