[cisco-nas] V92 modemcap for NP

[Aaron Leonard]

> We use the following modemcap for our V92 MICA (2.9.4.0)

> modemcap entry 
>  MICA_2940:MSC=&F&D2S54=16584S0=0S29=12S21=15S62=8S63=3S34=18000S40=10S10=50

MICA docs:
http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/5300/sw_conf/sw_ports/at_set/atcmnds.htm

Translating:

S54=16584
       16384 - enable V.92/V.44 on IOS that doesn't support capabilities exchange
       256 - add 0.5 to the SQ threshold (default)
       32 - PC-tel workaround
       8 - enable power control (default)
       4 - 4-point training
S0=0    autoanswer after 0 sec.
S29=12  V.92 automode
S21=15  V.44, V.42bis, MNP5 enabled
S62=8   Allow V.92 MoH for up to 4 minutes
S63=3   Enable QC with ANSpcm @ -12dBm
S34=18000 Fall forward after 3 good minutes
S40=10  Disconnect after 10 consecutive retrains
S10=50  Hangup after 5 sec carrier loss

> Is the following modemcap the right one for NP (0.8.3.0), if we want to have the same
> modem behaviour?

> modemcap entry NEXTPORT-V92:MSC=&F&D2S29=12S62=8

NextPort docs: http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/atnextpt.htm

Leaving out the default settings and the ones that don't apply to
NextPort, I'd use:

&FS0=0S62=8

If you want NextPort to receive at a more conservative rate (not normally
needed; NextPort does a good job by default of selecting its receive
rate), set S76 to 1, 2 or 3.
