MODULE
The CELP Voice Channel Module consists of two subassemblies, the
CELP base card and piggyback card. The CELP base card is a standard
GDC channel card 9 in. x 6.25 in. (22.86 cm x 15.88 cm) with edge finger
connections to the harness card on the opposite side to the front panel.
The CELP Voice Channel Module piggyback card is 6 in. x 4.6 in. (15.24
cm x 11.43 cm). It mounts onto the base card with the component side fac-
ing down via two sockets. Standoffs provide 0.5-inch (1.27-cm) spacing be-
tween the cards.
The CELP Voice Channel Module mounts into an empty channel slot in
the TMS-3000, TMS Compact, Univ. MM+ V4 or MINIMUX TDM.
Connections to the 4-wire VF line are made via standard GDC voice
channel cables (refer to Table 2-2).
