Multi-Tech Systems MT2834BA Carrier Detect Response Time, S10 Carrier Loss Disconnect Delay Time

Page 61

Chapter 6 - S-Registers

S9

Carrier Detect Response Time

Unit:

100 mSec.

Range:

1-255

Default:

6

Description:

S9 sets the time delay between when the modem first detects a valid incoming

 

carrier signal and when the modem turns on its Carrier Detect circuit. The default

 

setting is 600 milliseconds, or six units of 100 mSec each (Decimal 6). S9 may be set

 

for up to 25.5 seconds.

S10

Carrier Loss Disconnect Delay Time

Unit:

100 mSec.

Range:

0-255

Default:

7

Description:

S10 sets the time a carrier signal must be lost before the modem disconnects. The

 

default setting is 700 mSec, or seven units (Decimal 7) of 100 mSec. Maximum delay

 

is 25.4 seconds (Decimal 254). Setting the S10 value to 255 causes the modem to

 

not disconnect with loss of carrier. (This S-Register applies at speeds of 2400 bps

 

and less.)

S11

Tone Dialing: Tone Spacing and Duration

Unit:

1 mSec.

Range:

1-255, 80-255*

Default:

70, 80*

Description:

S11 sets the speed of tone dialing (spacing and tone duration times). The default

 

value is 70 units (Decimal 7) or 80 units, where each unit is one mSec, meaning that

 

each tone is on for 70 mSec with a 70 mSec pause between each.

 

The minimum S11 value allowed by most telephone systems is 50 mSec (50 units).

 

Very few telephone systems can handle anything faster than that. The maximum S11

 

value is 255 mSec (255 units).

S13

Remote Configuration Escape Character

Unit:

ASCII Character

Range:

0-127

Default:

37 (%)

Description:

S13 defines the remote configuration escape character (which becomes your

 

modem’s remote configuration character). The default is three percent symbols

 

(%%%). When the S13 character is entered three consecutive times from a remotely

 

connected site, your modem responds with its Remote Configuration procedure.
