DCP Mod e 2 req uires external hard ware to translate d ig ital 
transmissions to analog , b ut it works with most DEFINITY switc h 
c onfig urations. 
3. The DEFINITY AUDIX system uses EIA RS-232 Async hronous 
p rotoc ol to c ommunic ate with other AUDIX systems in a DCP 
Mod e 2 c onnec tion. Some d oc umentation for Luc ent Tec hnolog ies

In a DCP Mod e 2 c onnec tion, the DEFINITY AUDIX system c onnec ts to a 
DCP p ort on a TN754 c irc uit pac k. It then c onnec ts to an analog p ort in 
the switch’s analog trunk group via a data module and a modem. 
Customers c an use this c onnec tion with any DEFINITY or System 75 
switc h release. Fi g u re  2 - 3

Other DCP Mod e 2 c onnec tions may b e availab le for switc h releases 
earlier than 7.1. See 
DEFINITY AUDIX System — Dig ital Networking, 
585-300-534, for more information ab out DCP Mod e 2 c onnec tions in 
these switc hes.
!CAUTION:
Op erating the DEFINITY AUDIX system in a DCP Mode 2 Dig ital 
Networking  c onnec tion with hig her numb ers of sub sc ribers will 
sig nific antly degrade the system’s p erformanc e. The c onfiguration 
for a DCP Mod e 2 c onnec tion c annot exc eed  the following  limits:
— 10 remote nod es
— 100 local subscribers

Operating Requirements
Bec ause the DEFINITY AUDIX system operates inside the c ustomer’s 
switc h, it requires some of the switc h’s resourc es to op erate.
Space Requirements
The DEFINITY AUDIX system oc c up ies two universal p ort slots in a 
DEFINITY or System 75 switc h or one slot in a CMC.4 The TN568 c irc uit 
p ac k c onnec ts to the rig ht-hand  slot on the b ac kp lane, while the MO 
d isk d rive, the hard  d isk d rive, and  other c omp onents p hysic ally b loc k 
the left-hand  slot.

Ta b l e  2 - 2 shows the system’s physic al dimensions.
Power Requirements
The DEFINITY AUDIX system d raws its p ower from the 5 volt and  -48 volt 
b uses on the switc h’s b ac kplane. Ta b l e  2 - 3 shows the power the 
DEFINITY AUDIX system req uires from the switc h.
Environmental Requirements
The switc h and  the DEFINITY AUDIX system g enerate heat as they 
op erate. If the op erating  environment for the system and  the switc h is 
not p rop erly ventilated , this heat c an c ause these systems to 
malfunc tion. Their op erations c an also b e affec ted  b y other 
environmental c ond itions, suc h as humid ity and  air q uality. 
Switc h doc umentation id entifies spec ific  guidelines for the switc h’s 
op erating  temp erature and  environment. Generally, the c ustomer should  
use these g uid elines for c reating  a suitab le op erating  environment for 
the DEFINITY AUDIX system and  p rotec ting the system from harmful 
environmental c ond itions. The following  g uid elines rep resent the 
rec ommend ed  environmental c ond itions for DEFINITY switc h Release 
7.1 and  DEFINITY AUDIX system Release 4.0. See the system 
d esc ription for the c ustomer’s switc h for more information about 
environmental req uirements.
