IMA Uplink Card Connector Pinouts
The IMA uplink has a RJ48M 50-pin Telco connector with 8 Tip/Ring and
8 Tip1/Ring1 connections that conforms to ANSI T1.403-1999. Paradyne offers an octopus cable for use with the IMA uplink (Feature No. 8026-F1-001 for Models 8026 and 8028, and Feature No. 8027-F1-001 for Model 8027). These cables contain a required ferrite to meet EMI requirements. If purchasing other Telco cables, you must attach the supplied ferrite and cable tie as shown below. Contact your service representative for more information.
When connecting the Telco cable, a .87-inch long panhead screw and cable tie must be used to mount the cable to the 50-pin Telco connector as shown below.
