EDTB E1 Servis card

Description

The EDTB board is a 16-channel E1 interface board for the transmission of upstream services or access to subscribers. Up to six EDTBs can be installed in the adjacent slots of a rack.

The basic working principles of the EDTB board are as follows

• The control module controls and manages the EDTB board
• The line module provides the E1 line interface and processes the E1 frame format
• The conversion module performs the rate conversion between the 2 M HW and the 16 M HW
• The power module supplies power to each functional module of the board
• The clock module provides clock signals for each functional module of the board
