ITU-T V.59 PDF

This Recommendation specifies a series of Modem Managed Objects (MMO), which can be used to diagnose modem connections on the Public Switched Telephone Network for performance and statistics. This information is only valid from the beginning of the last connection until the start of the next connection. These MMOs are relevant to information exchanged across standardized interfaces.

This Recommendation does not define the DTE to DCE management process.

The set of managed objects includes:

a) Modem Identification;

b) Modem Capabilities;

c) Modem Selected Mode;

d) Modem Diagnostics;

e) Line Conditions;

f) Call Progress;

g) Protocol Performance;

h) DTE/DCE interface status.

NOTE – There is some similarity between the contents of this Recommendation and that of ITU-T V.58. ITU-T V.58 defines a management model for V-series DCEs and was designed within the scope of the Telecommunication Management (TMN) activity defining objects required for the management of Network Elements (NE). This Recommendation is intended to provide a standard way for untrained modem users to extract diagnostic information from modems which could be passed on to a third party e.g. Internet Service Provider (ISP). Where ITU-T V.58 is used as a reference and if the same attributes are used in this Recommendation, this is indicated.

Recommendation version

For the purposes of forward and backward compatibility, this Recommendation is assigned a version number that may be included as one of the diagnostic items.
