The following illustration shows the connectors located on the rear panel of the 675e units.

The following ports are located on the backside of the 675e.
The LAN interface uses an Ethernet port that conforms to the IEEE 802.3 and 802.3u protocols and supports 10 or 100MBps half-duplex data rates on category 3 (10MBps) or category 5 (00MBps) twisted-pair wire at a distance of up to 100 meters or less. The Ethernet connector is an RJ-45. The following table shows the connector pinouts.
| Pin | Signal |
|---|---|
1 | TXD+ |
2 | TXD- |
3 | RXD+ |
6 | RXD- |

The management port uses an RJ-45 connector.
The connector pinouts for the management port are shown in the following table.
| Pin | Signal |
|---|---|
4 | Ground |
5 | RX |
6 | TX |

The Asymmetric Digital Subscriber Line (ADSL) port uses an RJ-11 connector. The following table shows the connector pinouts for the ADSL connector. The sections that follow illustrate the ADSL connector and the Carrierless Amplitude and Phase Modulation (CAP) RADSL transceiver specifications.
| Pin | Signal |
|---|---|
3 | Ring |
4 | Tip |

The CAP RADSL transmission specification is shown in the following table.
| Type of Device | Specification | Downstream | Upstream |
|---|---|---|---|
7 MB router | Maximum Transmit Power | 22.7 dBm | 13.3 dBm |
| Rate | 952 Kbaud | 136 Kbaud |
| Spectrum | 240 - 1335KHz | 35 - 191.4KHz |
| Bandwidth | 1.095MHz | 156KHz |
