Customer-Supplied  External Alarm 
Equipment
The external alarm allows analog line ports to be used as additional external device alarm 
inputs to the DEFINITY System. This feature operates with all supported analog line 
circuit packs and with all maintenance circuit packs. This interface does not include a 
contact relay closure.
Each analog port used for this feature is administered as an external alarm connection. 
This administration includes information identifying the port, the external device 
connecting to the port, the alarm level assigned to the external device, and the “product 
identifier” of the adjunct or external equipment.
J58907AA-1  Personal Communications 
Manager (Forum)
The Forum Personal Communications Manager (PCM) is available outside the United 
States. The PCM uses a CommunicoreTM Mobility Manager that serves as an adjunct to 
DEFINITY ECS, to manage mobility. The system uses cordless telephone generation 2 
(CT2) technology, which is a global standard for wireless telephone service. This 
standard defines the radio interface between the Forum pocket telephones and the base 
stations in the system.
The PCM system manager provides superior system administration capabilities. The 
PCM personal communications manager can accommodate even the largest businesses. 
It has the following maximum capacities:
n500 wireless telephones
n126 base stations
n6 PRI interfaces to DEFINITY
n1 Sun workstation
n14.4 (minimum Baud rate) modem for remote maintenance
n2 maintenance telephones
n4 million square foot (371,000 square meter) coverage area
The PCM communicates to the DEFINITY ECS via a DS1 interface (ISDN-PRI).

DECT/ETSI-Compliant DEFINITY Wireless 
Business System for Non-US Markets
The DEFINITY Wireless Business System Digitally Enhanced Cordless 
Telecommunications (DECT) provides mobility management with an adjunct processor. 
The system uses the DECT/ETSI standard, which defines the interface between the 
wireless phones and the base stations.
The DEFINITY wireless business system (DWBS) has the following capacities:
n360 wireless telephones
n24 base stations
n12 E1 CAS links to DEFINITY
n1 administration PC
n1 modem for remote maintenance
The DWBS-DECT adjunct communicates to the DEFINITY ECS via a DS1 interface 
(providing E1 CAS).
RM0850HA100  Rectifier Module
The rectifier module is used in the J588980CH Power Distribution Unit. It operates as an 
integral part of a complete power system with battery backup. The modules operate in a 
redundant, high reliability mode to provide –48 VDC at 850 Watts to a common power 
bus.

Call Performance
Table 47 lists call processing performance for R8. This is also termed as Busy Hour Call 
Completion or BHCC. Realistic system capacity is what a DEFINITY ECS system, 
including a processor, TDM bus, Packet bus, etc., can support on a sustained basis. With 
allowances for system maintenance, administration, audits, etc., the system is still able to 
meet the various timing requirements, such as cut through. The numbers are based on 
0.57 call processing occupancy, allowing 0.28 for maintenance, administration, audits, 
etc., and 0.15 for normal bursts in traffic and for minimization of queuing delays in the 
processor. Keep in mind that the following chart is intended to be a guideline. The BHCC 
rate may vary depending on what features are being used with which DEFINITY ECS.
NOTE:
Call performance can vary with different customer applications. A Processor 
Occupancy Evaluation (POE) may be required. 
In the case of the csi model and si model, we allow for higher call volumes than would be 
expected from the number of stations, or in the case of ACD, the number of agents 
without having to perform a POE.

195 Additional Hardware to Use Features 
The system capacity for the r model is dependant upon the call mix and is bounded by 
processor occupancy and the number of stations. The number of agents in ACD 
applications and the TDM bus do not limit the BHCC rate as it does for the csi model and 
si model. In the case of the r model, when the expected call volume will exceed 70% of 
the System Capacity BHCC rate, a processor occupancy evaluation must be performed 
by the SDSC before certification of a new order or an upgrade.
The r model ISDN is limited by packet capabilities.
Table 48 lists response times for R8.
Additional Hardware to Use Features
Table 49 describes all features and any additional hardware required to use features. The 
hardware consists of circuit packs installed in carriers, devices in an auxiliary cabinet, and 
external devices. Not all feature applications require additional hardware.

Adjunct switch 
application inter-
face (ASAI) (Cat-
egory A only)Up to 8 interfaces are supported. 
R7si & later: the NetPkt, TN794 is required for ASAI applications. An 
TN570EI circuit pack is also required for system connectivity in mul-
tiple PN systems. R7r & later: the packet bus operation of the switch 
precludes requirement for a packet control or a NetPkt. In the R7 si/r 
and later switches, packet applications such as ASAI, require that a 
MAPD/LAN Gateway be provided, a maintenance/test circuit pack 
(TN771) in the PPN and TN570 E1 circuit packs for EPN connectiv-
ity. In a critical reliability system, a maintenance/ test circuit pack is 
required in each additional EPN.
The DEFINITY LAN Gateway is connected to the CallVisor Adjunct. 
Note: Older systems might have a BRI circuit pack installed for this 
application, however, the use of a BRI pack limits the Adjunct to a 
286 processor. This, a BRI circuit pack is not a recommended solu-
tion.
Note for csi: R6.3.2 and later csi models use the TN801B MAPD — 
the TN771 is not required. The R6csi model supports 120 mes-
sages/sec. If the C-LAN (TN799) is present in R7 and later csi mod-
els, throughput is increased to 240 messages/sec.

ATM port-net-
work connectivity
(Category A only)R7r or later only: ATM interface circuit pack, TN2305 or TN2306 
(replaces the TN570B expansion interface), software-selected OC3c 
or STM-1 facility.
Establishes calls between port networks as Switched Virtual Con-
nections (SVCs) based on Q.2931 signaling, as per the ATM forum 
UNI 3.1 specification. A private ATM network provides the inter-port 
network switching. Customers adopting this option no longer require 
switch node carriers and must replace all EIs with ATM circuit packs 
(hybrid EI- and ATM-based port network connectivity is not sup-
ported). DS1 converter remote-port networks are not supported. 
ATM CES Trunks
(Category A only)R7 or later only: Requires TN2305 or TN2306. Uses ATM Forum 
VTOA-0078 to support up to 8 ISDN-PRI emulated circuits over sep-
arate PVCs. Each circuit has 1 D-channel and 6 to 30 B-channels. 
Additionally, the TN799 is required for the csi switch model.

soleThis feature requires a port on a TN754B, TN2181, or TN2224 digital 
line circuit pack for each attendant console to be assigned. For reli-
ability, the attendant consoles should not be assigned to ports on the 
same TN754B circuit pack. For example, if 3 digital line circuit packs.

temVoice: AUDIX machine and appropriate ports on analog line circuit 
packs. 
Data control link: R7si uses the processor interface (PI) RS-232 con-
nector on the rear panel of the PPN control carrier and a data mod-
ule. If the PI connector is not available, a port on a digital line circuit 
pack and a data module are required in addition to a PI link. 
R7r: port on packet gateway circuit pack. AUDIX networking requires 
ports on 1 or more digital line circuit packs.
AUDIX (audio 
information 
exchange) 
embedded voice 
mail systemDEFINITY AUDIX assembly resides in 2 consecutive port slots for 
the si and r models (using the SCC and MCC cabinets). Two slots 
are also used in the CMC unless placed in slot 6 — then only one 
slot is used. Digital port mode does not require additional hardware 
for a data control link and supports only 16 AUDIX ports. Control link 
mode requires the same additional data control link hardware as an 
AUDIX adjunct listed above. The administration terminal can con-
nect via: direct connection, modems, ADU, G3-MA, and G3-MT. 
Control link mode is not available with R7csi.
