the TEL-14 to seize the line. The station can also pick up a call on the TEL-14
line.
When Matrix Control is disabled, stations cannot initiate telephone calls, and
can only talk on the telephone line after the line has already been seized by the
TEL-14. This may be desirable if the interface line is dedicated to manual
operation, or to answering incoming calls automatically.
Matrix Control will be automatically disabled if:
• The telephone line is automatically answered at the interface.
• The telephone line is manually seized at the interface by pushing the "Hook"
button.
To enable Matrix Control, set option switch S6-6 to ON.
Switch S6-7 Half-Duplex Disable: In extreme conditions involving very poor
telephone lines or conditions that cause instability and echo, acceptable
performance can be obtained by enabling automatic switching to half-duplex
conversation. In this mode the DSP controlling the echo canceling will
automatically determine whether full-duplex or half duplex will result in better
operation. To restrict operation to full-duplex, set option switch S6-7 to ON. To
allow half- or full-duplex modes to be automatically determined, set option
switch S6-7 to OFF. The factory default setting is ON, restricting operation to
full-duplex.
Switch S6-8 Normal / Test Mode: This switch is only active on the Line A card,
but serves both lines. Switch S6-8 should normally be left ON, enabling Normal
Mode.
Switch S1-1 Auto Answer Ring Count: The Auto Answer Ring Count
determines the number of times the telephone line must ring before the TEL-14
automatically answers it. The ring count can be set to either 1 ring or 4 rings. To
set the Auto Answer Ring Count to 1 ring, set option switch S1-1 to ON. To set
the Auto-Answer Ring Count to 4 rings, set option switch S1-1 to OFF. The
factory default setting is ON, providing an Auto Answer Ring Count of 1.
Switch S1-2 Sense Dial Tone: The TEL-14 can automatically disconnect from
the telephone line when it senses dial tone. If necessary, this capability can be
disabled. To enable automatic disconnects resulting from dial tone, set option
switch S1-2 to ON. Dial tone disconnects are automatically disabled for the first
10 seconds of outgoing calls to allow time to begin dialing, regardless of this
switch setting. To disable automatic disconnects resulting from dial tone, set
option switch S1-2 to OFF. The factory default setting is ON, providing an
automatic disconnect when the TEL-14 senses dial tone.
Switch S1-3 Sense Busy Tone: The TEL-14 can automatically disconnect from
the telephone line when it senses busy tone. If necessary, this capability can be
disabled. To enable automatic disconnects resulting from busy tone, set option
switch S1-4 to ON. To disable automatic disconnects resulting from busy tone,
set option switch S1-4 to OFF. The factory default setting is ON, providing an
automatic disconnect when the TEL-14 senses busy tone.
