DATA-CHL (Data Channel)
The four Data Channels (DATA-CHLs) provide a data communications interface
that allows data terminal equipment connected to port circuit packs to
communicate with software applications running on the system. Each DATA-CHL
represents a dial-up/dial-out asynchronous communications port that interfaces to
the TDM Bus. Data is transported between the terminal equipment and the
software application over the DATA-CHL. Data Channels may be used to support
the following features and functions:
■
Establishment of a connection over which to log CDR data to a printer or
other storage unit. This connection is called PRI-CDR/SEC-CDR
(PRI-CDR Link).
■
Establishment of connections over which to log PMS, Automatic Wakeup,
and Emergency Access to Attendant data to a Journal printer. This
connection is called PMS-PRINT/JRNL-PRNT (PMS Printer Link).
■
Establishment of a connection to a customer-owned PMS. This connection
is called the PMS-LINK.
■
Establishment of a connection to system printer. This connection is called
the System Printer Link (SYS-PRNT).
■
Establishment of connection(s) for up to two secondary administration
terminals.
■
Saving announcements from the ANN-BD (Announcement Circuit Pack).
■
Restoring announcements to the ANN-BD (Announcement Circuit Pack).
■
Maintenance testing of the DATA-CHLs.

<ext> is the extension of the Data Channel to be tested. The extension can be
determined by issuing the list data-module command from the administration
terminal. The resulting form provides a mapping from the 1CXXpp designation of the
Data Channel to its corresponding extension, where pp indicates which one of the four
Data Channels is alarmed (01, 02, 03, or 04) and C indicates the carrier on which the
alarmed Data Channel resides.
