LCOB-8 Board
8- Circuit Loop Start (LCOB-8) provides a ll outbound and inb ound ca ll sup ervision on the
nece ssa ry circuitry for the conne ction of eight CO lin es. Th e n omina l imp eda nce of ea ch
CO l ine ci rcui t is 6 00
.DTMF, dial pulse, or a combination of both may be used for
outb ound ca lls. Lin es 1 and 2 of each L COB- 8 are con nected to power- fail ports (on the
RJ-21X block) d uring p ower outage s. All conne ctions to the LC OB- 8 are ma de through a
24-p in champ amph enol-type connector.

2-Port Analog Adapter
A 2- Port Analog Ada pter is optionally ava ilable which will sup port m ost auxiliary
equipme nt within a bus ine ss en vironme nt such as fax m achines, ans wering de vices and
Single Line Telephones (SLT). Each adapter requires an unused digital station port and
will yield two a nalog de vice interface s.
The 2-Port Ana log Ad apter is a wa ll mount a pparatus tha t is powered f rom the KS U. T he
ada pter receives b oth voice cha nnels and data control from the KS U, over one pa ir of
wire s. T he 2- Port Analog Ada pter ge nerates + 30V D C a nd 20- 25Hz, 50V s quare wave
ringing fo r op eration of S LTs , f ax ma chine s, ans wering de vice s, and most mo dems . All
te rm ina tions are b y RJ-11 conne ction.
When used with the DTIB-8 (only), the analog Adapter utilizes the B1 channel for voice
tip/ring connectio n to one ana log station, and th e B2 cha nnel for the other. D chann el
provid es port control to and from the KSU. The ad apter p rovide s two D TMF re ceive rs
(one for ea ch an alog port) .
Third party ana log d evices conne cte d to th e 2-Port Ana log Ada pter must ge nerate DTMF
