SB-3614(V)/TT Automatic Telephone Switchboard
The SB-3614(V)/TT is a tactical 30-line analog switchboard which
can provide a variety of 2, 4, and 6 wire circuits. Subscriber
lines off the SB-3614 are 2-wire DTMF or Dial Pulse, and can support
TA-838 or STU-III telephones. Trunk interfaces are 2-wire for
long locals or PTT lines, 4-wire for the SB-3865 or TTC-39, and
6-wire for E&M signaling DSN via STU-5. Up to three SB-3614s
can operate in a stacked configuration. The 3614 can also be
operated with the SB-3865 in a hybrid stack. However, it should
be noted that no more than three switchboards total of either
type can be used in a hybrid stack. A limitation of the hybrid
stack is that an access code is required for dialing between the
two types of switchboards. The SB-3865 database also has the
capability to route only 30 subscribers to the SB-3614, including
the operator position. SB-3614 subscribers can access trunks
without operator assistance by dialing an assigned access code.
In all cases, incoming trunk calls are answered by the switchboard
operator and forwarded to the called party.
