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.
From the viewpoint of administration, the four DATA-CHLs on the TN798
Processor circuit pack are numbered 01 through 04. Each DATA-CHL may be
assigned a unique extension using the
add data-module [ <ext> | next ]

2. <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.
