CAUTION:
Do not plug the 120A3A into any circuit pack other than a TN464F or
TN767E (or later release/vintage) or TN2464 or Tn2313. Do not connect the
120A3A to any interface other than a 700A DS1 loopback jack.
Be sure the DS1 circuit pack is set for 24-channel operation (1.544 Mbps).
The 120A3A does not operate with the 32-channel interface. A switch on the
circuit pack or administration sets this option.

Always wear an anti-static wrist strap when installing a 120A3A module. Do
not touch the external alarm cable when it is connected to the 120A3A.
