  • Disconnect cause codes and progress codes

The disconnect cause code uses this format:

[name,]c=xxxx,p=yyyy,[ip-addr]

Name is the name of a profile. It can contain up to 64 characters. A name containing more than 64 characters is truncated, and '+' is added to the truncated name. The name appears for incoming calls only.

Xxxx is the disconnect cause code.
Yyyy is the connection progress code.
Ip-addr is the login host's IP address for Telnet and raw TCP connections (if applicable).

 
Code

Description
0 No reason.
1 The event was not a disconnect.
2 The reason for the disconnect is unknown. This code can appear when the remote connection goes down.
3 The call has disconnected.
4 CLID authentication has failed.
These codes can appear if a disconnect occurs during the initial modem connection.
10 The modem never detected DCD. (modem tones not being recognized)
11 The modem detected DCD, but became inactive. (disconnect at user end) If logs show predominately cause 11 and 185, and r= rate is unusually low...probably means customer has phone line problems-lines too noisy to hold connection, etc.)
12 The result codes could not be parsed.
These codes are related to immediate Telnet and raw TCP disconnects during a terminal server session.
20 The user exited normally from the terminal server.
21 The user exited from the terminal server because the idle timer expired.
22 The user exited normally from a Telnet session.
23 The user could not switch to SLIP or PPP because the remote host had no IP address or because the dynamic pool could not assign one.
24 The user exited normally from a raw TCP session.
25 The login process ended because the user failed to enter a correct password after three attempts.
26 The raw TCP option is not enabled.
27 The login process ended because the user typed Ctrl-C.
28 The terminal server session has ended.
29 The user closed the virtual connection
30 The virtual connection has ended.
31 The user exited normally from an Rlogin session
32 The user selected an invalid Rlogin option.
33 The MAX has insufficient resources for the terminal server session.  (Our modem racks)
These codes concern PPP connections.
40 PPP LCP negotiation timed out while waiting for a response from a peer.
41 There was a failure to converge on PPP LCP negotiations.
42 PPP PAP authentication failed.  (username or password wrong)
43 PPP CHAP authentication failed.
44 Authentication failed from the remote server.
45 The peer sent a PPP Terminate Request.
46 LCP got a close request from the upper layer while LCP was in an open state.
47 LCP closed because no NCPs were open.   (No TCP/IP installed or corrupt)
48 LCP closed because it could not determine to which MP bundle it should add the user.
49 LCP closed because the MAX could not add any more channels to an MP session.
These codes are related to immediate Telnet and raw TCP disconnects, and contain more specific information that the Telnet and TCP codes listed earlier in this table.
50 The Raw TCP or Telnet internal session tables are full.
51 Internal resources are full. (Our end - out of memory)
52 The IP address for the Telnet host is invalid.
53 The MAX could not resolve the hostname.
54 The MAX detected a bad or missing port number.
The TCP stack can return these disconnect codes during an immediate Telnet or raw TCP session.
60 The host reset the TCP connection.
61 The host refused the TCP connection.
62 The TCP connection timed out.
63 A foreign host closed the TCP connection.
64 The TCP network was unreachable.
65 The TCP host was unreachable.
66 The TCP network was administratively unreachable.
67 The TCP host was administratively unreachable.
68 The TCP port was unreachable.
These are additional disconnect codes.
100 The session timed out because there was no activity on a PPP link.
101 The session failed for security reasons. (trying to log in with same username multiple times)
102 The session ended for callback.
120 One end refused the call because the protocol was disabled or
unsupported.
150 RADIUS requested the disconnect.
160 The allowed retries for V.110 synchronization have been exceeded.
170 PPP authentication has timed out.
180 The call disconnected as the result of a local hangup.
185 The call disconnected because the remote end hung up. (If logs show predominately cause 11 and 185, and r= rate is unusually low...probably means customer has phone line problems-lines too noisy to hold connection, etc.)If logs show predominately cause 11 and 185, and r= rate is unusually low...probably means customer has phone line problems-lines too noisy to hold connection, etc.)
190 The call disconnected because the T1 line that carried it was quiesced.
195 The call disconnected because the call duration exceeded the maximum amount of time allowed by the Max Call Mins or Max DS0 Mins parameter on the MAX.
