Table 6-4 Show Modem Summary Field Descriptions
Field Description
Succ 60005
60,005 calls successfully trained up. The Cisco IOS saw “DSR” go
high (still does not mean that PPP negotiated successfully).
Fail 4678
4,678 calls came into the modem, the modem went offhook, but the
modem did not train up.
Succ Pct. 92%
The overall success percentage is 92%.
No Ans 8
Eight calls came into the modem but the modem did not go offhook
(CPU was too busy). Unless you misconfigured the NAS, this
counter should be very low (under 1% of the total calls).
