4-84 MAX 6000/3000 Network Configuration Guide
Configuring Individual WAN Connections
Configuring terminal-server connections
To influence the outcome for modem negotiation and data packetizing, you can set the
following parameters in Ethernet > Mod Config > Tserv Options:
For detailed information about each parameter, see the MAX Reference.
Example of a modem configuration
To set the maximum negotiable baud rate for incoming calls from analog modems:
1 Open Ethernet > Mod Config > TServ Options.
2 Set the maximum negotiable baud rate to 26400:
Ethernet
Mod Config
TServ Options
Max Baud=26400
3 Exit the profile and, at the exit prompt, select the exit and accept option.
Parameter Specifies
V42/MNP How the digital modems negotiate LAPM/MNP error control with the
analog modem at the other end of the connection. The modems can
request LAPM/MNP and accept the call anyway if it is not provided,
request it and drop the call if it is not provided, or not use LAPM/MNP
error control at all.
Max Baud The highest possible baud rate (3360). The MAX unit negotiates down
to the rate accepted by the far-end modem. You can adjust the
maximum rate to bypass some of the negotiation cycles, provided that
no inbound calls use a baud rate higher than what you specify here.
MDM Trn Level Modem transit level, which is the amount of attenuation in decibels the
MAX should apply to the line. When a modem calls the MAX, the unit
attempts to connect at the transmit attenuate level you specify.
Generally, you do not need to change the transmit level. However, if
the carrier becomes aware of line problems or irregularities, you might
need to alter the modem transmit level.
Users can change the default settings for their specific connections.
Increasing the attentuation level helps certain modems with near-end
echo problems.
MDM Modulation Modulation to use when answering calls on the unit’s 56K modems.
The possible settings are K56, V.34, and V.90.
Cell First Whether or not the unit first attempts cellular modem or conventional
modem negotiation when answering incoming calls. If the first
negotiation fails, the unit attempts the other negotiation.
Cell Level Gain level of the cellular modem.
7-Even 7-bit even parity on outbound data. Most applications do not use 7-bit
even parity.
Packet Wait Time Maximum amount of time, in milliseconds, that any received data can
wait before being passed up the protocol stack for encapsulation.
Packet characters Minimum number of bytes of received data that should accumulate
before the data is passed up the protocol stack for encapsulation.
