G703FE1-A is a single port access unit for Fractional E1 services. Data Port rates are selectable via DIP-switches, for any multiple of
64Kbps up to 2048kbps (Fractional models only). User data is
placed into the E1 frame, using only the required number of
timeslots. Timeslot assignment is accomplished according to
the Data Port speed and is selected by DIP-switches. The main
E1 link may be clocked from the recovered receive clock (LBT),
from the data port, or from an internal oscillator. The data
channel interface is RS530 standard. Adapter cables are
available for V.35, X.21 and RS449. The G703FE1-A 's DIP and slide switches, located on the side and front panels, provide for easy setup and control of all functions.
G703FE1-A model may be cascaded as an E1 Multiplexer. The unused channel timeslots will pass through E1/Rx to E1/Tx.
