I need to configure an AS5300 for dialin access to a corporate network. There will be a PRI circuit associated with a 1-800 hunt group. What is required to connect the AS5300 PRI interface to the service provider network (csu/dsu)?
Does anyone have a known working AS5300 configuration with PRI interface(s) for dialin that they can share with me as a reference?
Thank you in advance,
Dan

s29, s30, s31 are the S registers of interest here:
In order to apply a modemcap please refer to:

Mak,
I have used the modem-pool command to direct incoming calls to the appropriate mica modems (line), and the modemcap command to set the autoanswer to "immediate" and the s30 register to the appropriate maximum speed (1200/9600). This is desired in order to minimize the negotiation time for the dial client connection.
Below is a copy of the config. Would it be possible for you to review it and verify that I have configured the modem-pool and modemcap commands correctly?
Thank You,
Dan

In the modempool commands do not have any "-" between the numbers... keep the called number as 5555555555.
Apply the modemcap as follows:
router#conf term
router(config)#modemcap edit MODEMCAPNAME misc INITSTRING
router(config)#line BEGIN END
router(config-line)#modem autoconfigure type MODEMCAPNAME
Thanks, Mak.

Thank you, Mak. I corrected the called-number entries. The documentation I have read talks about beginning the init string with &F$D2. I have simply added S0=1200 and S0=9600 in the Misc field. I have also set the autoanswer (AA) field to 0. Is what I have sufficient to properly initialize the modems?
My goal is to minimize the connection time for the dialin users to have the modem answer as soon as it detects an incoming call, and not have to negotiate the connection speed. Is there anything else I need to consider?
Regards,
Dan

modemcap entry 9600:MSC=&f&d2s29=0s30=9600
This will train with the top modulation being V.34 at 9600 bps
modemcap entry v32only:MSC=&f&d2s64=5
This will train using only V.32 (top rate 9600 bps)...NOTE:By using the S64 register, MICA is forced to try ONLY the standard specified in S64 & if that does not connect then the call will fail, there is no fallback with s64.
Thanks, Mak.

The modemcap commands also have subcommands to set AA (autoanswer) and SPEED. Do these set the S0 and S30 registers?
04-10-2003 05:19 PM
Yes, you can add s0=0 or s0=1(we default to 2) if need be.
&f&d2s0=0s29=0s30=9600
Thanks, Mak.

Thanks again, Mak. I was having some difficulty yesterday getting a modem working on the aux port. Not quite sure if it's a problem with the modem, the aux port, or my configuration. I'm hoping to revisit it today with a new USR Sportster 33600 modem. Below is the latest version of my aux port config.

For USR, reverse telnet into the modem & add the following init string...have dip switches 3 & 8 down , rest up.
at&f1s0=1&c1&d1&a1&w
On the line try with & w/o the speed commands.
Thanks, Mak.
