(according to the ITU-T Recommendations G.742 and G.751). The firmware of the device may be updated by user. The instructions for updating the firmware may be found at the www.cronyx.ru web site. 1.2. Operation Data accepted from the digital interface port is placed into selected timeslots of the E1 stream for output through the E1 link. -

Page 20: Synchronization Modes
For E1 channel, the single clock source is used as a rule. The source of clock signal may be an internal oscillator of any E1 modem or external clock signal of any DTE. Examples are shown in figures below. © 2006 Cronyx... -
Page 21: Dte Emulation
The «Receive clock: Receive» mode is used when connecting to DCE devices receiv- ing external clock signal (ETC) from the digital port. In this case the pair of devices connected by digital ports (RS-232, V.35, RS-530, X.21) translates the clock frequency transparently. © 2006 Cronyx... -
Page 22: Dte Emulation, External Transmit And Receive Clocks
The receive and transmit data paths contain intermediate data buffers for converting the clock frequency by inserting or deleting HDLC flags. The data stream must contain HDLC packets with the number of delimiting flags not less than 2. Maximum available difference of frequencies is about 200 ppm. © 2006 Cronyx... - Page 23 Chapter 3.
