Dial Out User Statistics Window

Access Server Administrators’ Reference Guide 

This portion of the Dial Out User Statistics window (see 

 on page 130) contains statistics about the 

modem connection. It includes modulation, levels, and other modem-related statistics that are helpful when 
troubleshooting modem problems. This section covers only modem-type statistics, not ISDN connections.

Connection Modulation (doactModulation) 
The modulation type of the modem link (for example, V.34). The modem link can have these modulation or 
data types:

•

unknown(0)

•

v21(1)—V.21 modulation

•

v22(2)—V.22 modulation

•

v32(3)—V.32 modulation

•

v34(4)—V.34 modulation

•

k56(5)—K56 Flex modulation

•

x2(6)—X.2 modulation

•

v90(7)—V.90 modulation

•

v110(8)—V.110 modulation (not currently implemented)

•

isdn64(9)—ISDN 64 modulation

•

isdn56(10)—ISDN 56 modulation (not currently implemented)

•

12tp(11)—12tp tunneled multilink call

•

phase2(20)—Phase 2, an advanced state of modulation in v34 and higher

•

answerack(21)—acknowledgement phase of modulation

Tx Connection Speed (doactTxSpeed)
The connected speed of the modem link (for example, 28.8 bps). These values, in bits per second, range from 
300–33,600.

Rx Connection Speed (doactRxSpeed)
The connected speed of the modem link (for example, 28.8 bps). These values, in bits per second, range from 
300–53,000.

Error Correction Protocol (doactErrorCorrection)
The modem error correction scheme used during this call.

•

None—No error correction on the call.

•

V42—Error correction mode

•

V120—Mode for ISDN B
