Primary Rate Interface Board (PRIB)
The PRIB board allows the network connection to a Primary Rate ISDN
interface. It provides one Primary Rate Interface circuit. Each circuit is
compris ed of 23 be are r channe ls an d one da ta channe l (23B+D). The
sys te m i nt er pr et s a ll B cha nnel s as tr unks/l in e a ppe ar ances . A m axim um
of six PRIBs can be installed into the system. The PRIB uses 24 time slots.
The PRIB conta ins an ISDN interfa ce circuit, control circuitry , an d
synchronous clock control circuits . D TMF tone de te ction units can be
ins ta ll ed opt iona ll y on t he P R I B . T he P R IB a c c ept s two DT MF -A boa rds .
The PRIB has 8 LED s on the f ront e dge of the PCB which ind icate s e rrors
of ISD N line , in- use status, and synchronous clock ena ble s ta tus .

Basic Rate Interface Board (BRIB)
This interface provides four Basic Rate Interface circuits. Each circuit is
compris ed of two b earer ( 64Kbps ea ch) an d one da ta (16Kbp s) cha nnels
(2B+ D). Whe n a BRIB is programme d into theTri ad 3system, the system
inte rprets all B channe ls as trunk s. Thus , one BRIB which contains f our
2B+ D ci r c uit s p rov ide s ei ght li ne app ea ran ce s to theTr iad 3sys te m. A
maximum of e ight BRIBs ca n be installe d into the sys te m (64 B chan nels).

El ectron ic Key T el ephon e Service
Electron ic ke y te le phone se rv ice (E KTS) is a fea ture that can be prov id ed
on BRI ISDN to simulate standard analog DID lines. This allows several
differe nt numbe rs to be sha re d b y a single BRI circuit.
Due to the decline in telep hony tariffs, there is an increas in g de mand for
BRI ISDN features. A BRI circuit allows two simultaneous calls to be
handled, d ue to its techn ical s pecification. BRI circuits have two
B-Ch anne ls at 64 kilob ytes per se cond a nd one D- Chann el at 16 kilobytes
pe r s ec ond. The Bea re r (B) Chann el s ar e d es igne d for P CM (v oic e ) and t he
Data (D) Channe l is de signed to carry in form ation spe cific to e ach
incom ing and/or outgoin g call.
TheEKTSfeatureallowsasingleISDNServiceProfileIdentifier(SPID)or
B-Channel to support multiple directory numbers. A SPID is a number
that telephone company switching equipment uses to track
configura tion informatio n for e ach terminal ad apter conne cte d to a n
IS DN te le phone line . The telepho ne com pany should p rov ide S PIDs at
thesametimethattheISDNdirectorynumbersareassigned.Adirectory
numbe r is anothe r te rm for a te le phone numb er.
If an applica tion re quires E KT S, be awa re that BRI ISDN hand le s a bus y
numbe r differe ntly than a D ID circuit. Whe n the calle d numb er is b usy,
BRI will issue a busy signal, but a DID circuit will ring another line in the
circuit. The bus y s igna l is provided by the telep hone company , theref ore
the c a ll i s no t p re se nte d t o t he Vo da vi te le pho ne s wit c h a nd i t is no t
forwarded to voice mail. For example, a caller dials 480-443-6000 and is
connected to the extens ion. While the firs t caller is still connected , a
second caller dials the s ame number. The secon d caller will receive a bus y
signal that is provided by the telephone company.
In a nor mal BRI appl ica ti on, t wo nu mber s are as si gned to e ach BRI ci rcui t,
which consists o f 2 chann els. There can be a m aximum of 4 circuits
equipp ed to handle 8 channe ls pe r BRIB. This is a d irect numb er-to-
channe l re la tionship without huntin g capa bility . Most circuit providers
offe r a n opti onal“hunting”f eat ur e cap abi li ty on BRI ci rcui ts . Thi s op ti onal
fea ture allows numb ers to h unt for id le chann els on the BRIB up to a
maxi mum of 8 chan nel s p er BRIB, as sumi ng f our BRI ci r cu its w er e
ins ta ll ed . I n E KTS app li cat ions , you can h ave a maxi mum of 6 4 DI D
numbe rs hunt to one BRIB. Hu nting ca nnot be accomplishe d be tw ee n
