Notes: 1) RJ11 Pin assignments reflect a 6-pin connector. Tip and Ring are always the center pins of the RJ11 Jack.

2) CTR21 requires the modem to be able to dissapate over two Watts in come applications where the integral

current limiting circuit is activated. The XE1414C requires a heat sink to be added to dissapte this addi-

tional power.
