connect the switch and this phone. On the newer switches that

a TN762B Hybrid pack must be used with the Universal carrier
for this purpose. Depending upon the actual hardware configu-
ration, DEFINITY G2 - G2.1 and G2.2 may utilize either an
ANN17B or TN762B pack. In either case, the latest vintage
packs are recommended.
