E1 Port in option on –ET Product release
E1 port allows connect an E1 Unframed G.703 or Framed G.704 through a RJ45 socket or a double BNC.
Link Type:
E1: Type 2048 MBps G.703 or G.704 framed.
Framed Type:
Unframed: G.703 all the data are used and transmitted and the frame is not analyzed.
Framed: G.704 Time Slot 0 is necessary for the synchronization, and only the Time Slots selected are transmitted.
Multi-frame: G.704 Time Slot 0 is necessary for synchronization, and Time Slot 16 is analyzed to find the ABCD CAS bits for each
channel. This mode is not operational with current release 1.07.
Receiver Sensitivity:
Short Haul: the LOS detection threshold is based on cable loss of 12 dB to 18 dB.
Long Haul: the LOS detection threshold is based on cable loss of 30 dB to 45 dB.
Interface type:
Balanced RJ45/120: to use the RJ45 socket at standard 120 Ohms impedance.
Unbalanced BNC/75: to use the BNC connectors at standard 75 Ohms impedance.
CRC4:
Yes: enable the detection of the CRC4 bits for the framed transmitted on the E1 link.
No: disable the detection of the CRC4.
Clock mode:
One: transmit and receive clocks are based on the same source.
Two: Can be used in co-directional mode when clocks are provided on two E1 ports with a GPS reference clock or stratum clock on both
sides.
Clock source:
Recovery: the clock pulse is created from the remote CIP with Phase Locked Loop components and software principle.
Loop-back: the clock pulse is exactly the clock on the E1 port.
Internal: used to check configuration, and when no reference clock is present on the system.
The current application is based on a loopback on one CIP and recovery clock mode on the remote CIP.
Associated Bundle ID:
Only available in Recovery clock mode, this is the number of the Bundle created on the Bundle screen.
Network Type:
This is the model used to simulating distribution of the packet delay variation on the network
Router-based.
Switch-based.
DSL-based.
