4.03 The

that

derived metallic simplex leads. The

circuit is abalanced

bridge-type

detector

that

senses differential voltage

changes

across four

400-ohm

resistors

that

replace the

four

windings

the

relay used in conventional relay-type

sets. The differential voltage changes are sensed

and

directly

coupled

to an integral dial-pulse com-

pensator. The

compensator

introduces

aslight

delay

that

the

6008C

ignores

spurious signals.

Also, to minimize dial-pulse distortion, the

compen-

sator

adjusts

for

nonsymmetrical switching of the

E&M

signaling

relay. An E&M

signaling

relay

(K1)

provides the local E-lead

output

(in the

OX1

mode)

the

local M-lead

output

(in the

OX2

mode). The

E&M

signaling

relay

(K1)

is operated during busy

not

operated during idle. Resistor-capacitor

protection is provided

for

the relay contacts.
