8 Press the TAB key to save the settings.
9 Click the V.90 Access Parameters tab.
The V.90 Access Parameters screen appears.
Connect Rate Lets you specify the initial speed (in bits per second) for the modem to connect. Set to
the maximum permissible value for best results. Permitted values: 57600, 38400,
19200, 9600, 4800.
Note : This is the initial rate; the actual rate is always negotiated.
Dial Retries Lets you set the number of attempts the system must make when trying to connect
before considering the connection non operational.
The default value is 3 .
Dial Interval Lets you set the interval, in seconds, between successive connection attempts.
The default value is 60 .
Number Of Rings Lets you specify the number of rings the Business Communications Manager waits
before determining that the far end of the connection is not answering.
The default value is 1 .
Speaker Mode Lets you enable or disable the speaker during initial link establishment.
IP Header Compression Lets you enable or disable IP header compression. To function, the receiving end must
also use this feature.
Software Compression Lets you enable or disable data compression in the software, instead of the modem.
For dial-up connections, Unified Manager uses Microsoft Point-to-Point Compression
algorithm (MPPC).
Hardware Compression Lets you enable or disable data compression in the hardware instead of the software.
PPP LCP Extensions Lets you enable or disable the following PPP Link Control extensions: Time-Remaining
and Identification.
The default value is Enabled .
Disconnect Time Enter the interval, in seconds, during which the modem interface disconnects when
there is no traffic.
Select 0 if you want the Business Communications Manager to close the connection
when the far end hangs up.
Select PersistentConnection if this connection is intended to always be connected.
Note : If you have more than one Trap Community Entry configured with this dial up
interface, using a very small number for the Disconnect Time will put you at risk of a
racing condition. To reduce the racing condition, enter a larger value for the Disconnect
Time.
