ONE and  c onvert b etween the RS-232 c ommunic ations p rotoc ol used  b y 
p erip herals and  the DEFINITY Dig ital Communic ations Protoc ol (DCP). Possib le 
peripherals include AUDIX adjunct equipment and terminals, serial printers, 
c ustomer-sup plied  terminals and  host c omp uters, c all detail-rec ord ing  (CDR) 
devices, and pooled modems.  The following data modules are described in this

DCE equip ment to the ISDN network using  an RS-232 or V.35 interfac e and  
an RS-377 automatic  c alling  unit. 
Understanding  RS-232 
communications
To install a d ata mod ule, you have to set up  the d evic e to work with RS-232 
devices.

The RS-232 c ommunic ations p rotoc ol d efines a c ommunic ations link as a Data 
Communic ations Eq uipment (DCE) d evic e and  a Data Terminal Eq uip ment (DTE) 
d evic e c onnec ted  b y an RS-232 c able. The send  and  rec eive p ins on DCE 
eq uip ment (p ins 2 and  3) are reversed  on DTE eq uip ment, so that the DCE 
transmit p in c onnec ts to the rec eive p in of the DTE and vic e versa.  
Generally, the term DCE is ap p lied  to d evic es that med iate b etween c ustomer 
eq uip ment and the c arrier or network. Suc h d evic es inc lud e mod ems, d ata 
mod ules, and  data units. DTE d esc rib es devic es that p rovide a user interfac e for 
d ata c ommunic ations, suc h as d umb  terminals and  PCs. When c onfig ured  as 
DTE, d ata mod ules are used  for async hronous mod em p ooling . When c onfig ured 
as DCE, d ata mod ules are analog ous to mod ems in that they link a devic e suc h 
as a terminal or PC (DTE) to DEFINITY.   
To install a d ata mod ule c orrec tly, you identify the c onnec ted  eq uip ment as DCE 
or DTE and  d o one of the following : 
n
Config ure the mod em for a DTE or DCE c onnec tion
n
Install a null-mod em c onverter

Installation Procedure
To install a typic al d ata mod ule, you p erform the following  tasks:
1.Obtain Req uired  Eq uip ment
2.Sett Hard ware Op tions (must b e c omp leted  b efore you ad minister or 
p hysic ally c onnec t the d ata mod ule)
3.Connec t Data Modules
4.Ad minister the DEFINITY ECS for Data Mod ules (c an b e c omp leted  either 
b efore or after you physic ally c onnec t the d ata module)
Obtain Required Equipment
To p hysic ally c onnec t a d ata mod ule to the system, you need  the following p arts.
n
105C/D Isolating  Data Interfac e (if c onnec ting  to a DC c ab inet)
n
EIA-232-D (RS-232-C) c ab le with a male c onnec tor (for the d ata mod ule) 
and  the c orrec t c onnec tor for the p erip heral eq uip ment
The c ab le c onnec ts the PC to the d ata mod ule
n
Null-mod em c onverter (op tional)
n
V.35 c ab le with c orrec t c onnec tors (not req uired  b y all systems)
n
D8W telep hone c ord
The c ord  c onnec ts the d ata mod ule’s LINE jac k to the DEFINITY wall jac k. 
n
DCP telep hone and  D8W c ord  (op tional)
The D8W c ord  c onnec ts the telep hone to the d ata mod ule’s PHONE jac k.
n
Suitab le auxiliary p ower supp ly if the op tional telep hone is installed  (D7AP 
p ower c ord  and  400B2 ad ap ter in the US, international p ower sup ply, 
suc h as the MSP-1, elsewhere).
You must have ac cess to the administration console of the DEFINITY, either 
throug h a terminal and  keyb oard  or throug h a PC.
A b reakout b ox for RS-232 interfac es may p rove help ful in some c ases. The RS-
232 b reakout b ox help s you to identify the pin c onfig uration of the RS-232 
interface on the equipment you are trying to c onnect. 
Sett Hardware Options
Dep end ing  on the d ata mod ule, you may have to set various c onfig uration 
op tions using  hard ware switc hes, software c ommand s, or b oth. You must set the 
hard ware op tions b efore you administer or p hysic ally install the d ata mod ule.

Setting 7400A Data-Module Hardware Options
Most c onfig uration op tions are c ontrolled  b y c ommands entered  on the front 
p anel of the 7400A. But you have to make hard ware c hang es when you want to 
set up  the 7400A d ata-mod ule for use in a mod em p ool or as a p iec e of d ata 
c ommunic ations eq uip ment. In a mod em-p ool, the d ata mod ule op erates as 
d ata-terminal eq uip ment (DTE). In most other ap p lic ations, it func tions as data 
c ommunic ations eq uip ment (DCE). You have to set the c orrec t op erating  mod e 
for the d ata module b efore you c an ac c ess the menus for the remaining  
configuration tasks. 
To c hang e the op erating  mod e of the 7400A from DCE to DTE (or vic e versa), you 
c hang e the p osition of a small c irc uit b oard  (the Elec tronic  Ind ustries Assoc iation 
c onnec tor b oard ) insid e the c ase. See Fig ure 11
 and  p roc eed  as follows.
!WARNING:

Before handling  any elec tronic  hard ware, b e sure to wear a g round ing  wrist 
strap  or other static -d issip ating  d evic e. Do not touc h exp osed  c irc uitry or

1. Unp lug  the d ata mod ule from the p ower rec ep tac le. 
2. Remove the ac c ess p anel on the top  of the c ase b y g rasp ing  the rear lip  
of the p anel and  p ulling  sharp ly up ward.
3. While fac ing  the front of the d ata module, loc ate the small EIA c onnec tor

c irc uit b oard  p oints to it.
