NetVanta 1235P Hardware Installation Guide
RJ-45 Pinouts for ActivReach
The NetVanta 1235P has 24 10/100Base-T Ethernet ports that support both standard and ADTRAN's
ActivReach Ethernet. The NetVanta 1235P supports standard 2-pair 10/100Base-T over CAT 5 and 4-pair
1000Base-T over CAT 5e. When in standard Ethernet mode, standard Ethernet pinouts apply.
When used in conjunction with the NetVanta ActivReach Media Converter (P/N 1702595G12), the NetVanta
1235P converts standard Ethernet to ActivReach Ethernet, which supports rates of 10/100 Mbps over 1-, 2-, and
4-pair infrastructure wiring. The following diagram illustrates the pin connections for ActivReach applications.
The pinouts apply to both the switch port and the ActivReach Media Converter.
• For 1-pair ActivReach applications, pair A must be connected between the switch and
Media Converter. For NetVanta 1235P to NetVanta 1235P ActivReach connections, this
requirement does not exist.
• For 2-pair ActivReach applications, pair A must be connected, and either pairs B, C, or
D can be used in conjunction with pair A.
• Polarity inversion within a pair does not affect ActivReach performance.
For applications requiring connection into a single RJ-21, a hydra interconnect cable (P/N 1702595G14) can be
used. The hydra interconnect cable is suitable for 10 Mbps applications only. See
hydra cable's 50-pin Champ connector pinouts.
