The Embedded Operations Channel (EOC) is used to transfer data from the exchange
to the terminal side and vice versa without occupying B- or D-channels. It is used to
transmit diagnostic functions and signaling information.
EOC-data is inserted into the U-frame at the positions M1, M2 and M3 thereby permitting
the transmission of two complete EOC-messages (2 x 12 bits) within one U-superframe.
With a MON-0-command a complete EOC-message (address field, data/message
indicator and information field) can be passed to the U-transceiver.
The EOC contains an address field, a data/message indicator and an eight-bit
information field. With the address field the destination of the transmitted message/data
is defined. Addresses are defined for the NT, 6 repeater stations and broadcasting.
The data/message indicator needs to be set to (1) to indicate that the information field
contains a message. If set to (0), numerical data is transferred to the NT. Currently no
numerical data transfer to or from the NT is required.
From the 256 codes possible in the information field 64 are reserved for non-standard
applications, 64 are reserved for internal network use and eight are defined by ANSI for
diagnostic and loopback functions. All remaining 120 free codes are available for future
standardization.
