multiplexer AN-STM-1-IP, make point-to-multipoint application ,and point to
point of connection, Typical application is shown in Fig 1.3-1~Fig 1.3-3.
Figure 1.3-1 Convergent Application
Figure1.3-2 Typical application of wireless network
Fig. 1.3-3 The typical application of cable network
AN-TDM-IP-1E1/2E1-A could cooperate with wireless bridge of most
manufactories in wireless network application use, At present, some the sold wireless
bridge transmission bandwidth change with the Ethernet packets, some Bridges will
introduce the packet delay jitter, when work with the different wireless bridge, need
to adjust E1/T1 signal seaied length and jitter, in order to get the best transmission
effect.
Note : This equipment is used together with the wireless Bridges, usually
through reticule and outdoor antenna system of wireless bridge connected,
there is lightning risk at this time, must be in an upward in combination of
Ethernet lightning protection protector, otherwise lightning will make seriously
damage to the equipment, danger to the staff .
1.4 Timing modes
To emulate a transparent E1 channel over a packet network, the
AN-TDM-IP-1E1/2E1-A not only conveys data stream content correctly from the
source to the destination, but also recovers the E1/T1 timing from the source at the
Manuel de l'usager du Mux IP vers 2xE1
www.hypercable.fr

AD-net Technology., CO LTD
www.ad-net.com.tw -3-
destination accurately. Packet networks do not provide such built-in timing
transparency mechanism as TDM networks do. AN-TDM-IP-1E1/2E1-A uses its
proprietary algorithm to reconstruct the E1 clock at the destination. The recovered
clock is of very high quality, with low jitter and wander. Typical frequency offset is
within ±5ppm, and jitter is below 0.1UI. It can be adopted in most applications. This
timing mode of rebuilding the E1 clock at the destination is called Adaptive Timing.
For applications where separate clock distribution network exists, another
timing mode, Loop back Timing, may be used for maximum clock quality. In this
mode, AN-TDM-IP-1E1/2E1-A rebuilds the E1/T1 output code stream using the
clock extracted from E1/T1 input signals. AN-TDM-IP-1E1/2E1-A built-in memory
can eliminate the wander completely. It will switch to Adaptive Timing automatically
once the input signals are lost.
The two timing modes of AN-TDM-IP-1E1/2E1-A are showed in Fig.1.4-1.
Fig.1.4-1 E1Timing modes
Correct timing mode setting is important for smooth operations. In most cases,
setting both units to adaptive timing mode is sufficient. But sometimes, setting one
unit to loop timing mode may work better. For example, setting the
AN-TDM-IP-1E1/2E1-A unit connected with the clock master (such as local
exchange) to loop back mode, and the other unit connected with the clock slave
(such as PBX remote module or PCM terminal) to adaptive mode, is probably
better than setting both to adaptive modes. It’s better to set the both sides
AN-TDM-IP-1E1/2E1-A to loop back timing mode when the both sides equipments
use synchronous master clock. In another case, set the both sides
AN-TDM-IP-1E1/2E1-A to adaptive timing mode when the both sides equipments
use asynchronous master clock.
One typical error in telecom applications is to connect two communication
devices that are both clock slaves. Neither will AN-TDM-IP-1E1/2E1-A support
such operation no matter how the timing modes are set.
Note: The Lock Clock usually takes several minutes to stabilize. During
that period, clock drift may exceed the limit, errors and slips may occur.

2.1 Function Description
The core of AN-TDM-IP-1E1/2E1-A is the TDM/Packet processing unit. It
truncates E1/T1 data stream, and encapsulates the data into Ethernet packet with or
without IP headers. The packets are passed to the Ethernet switch unit via MII
interface, and are sent out through the uplink ports.
In the reverse direction, packets from the uplink ports are sent to the
TDM/Packet processing unit for reassembling the original E1/T1 data stream, and
outputting via E1/T1 interface. TDM/Packet processing unit need to process the
reassembled data to recover the E1 clock which is the key element of the device.
Very sophisticated algorithm is used to ensure that the reconstructed clock will meet
the stringent requirement of TDM applications. The most important parameters are
bit rate, jitter, wander, and signal delay.
The user can modify various operational parameters through Network
Management.

not.
4.1.5 E1/T1 Alarm LED ON
There are two groups of LEDs, PKT LOS and LOS for E1 alarms LEDs.
When E1 LOS LED is on, loss of E1 signal fault is detected by AN-TDM-IP.
Possible causes include:
The downstream equipment such as telephone exchange or PCM terminal
is powered off.
The E1 cable connection looses or broken.
E1 LOS LED blinks when respective input E1 signal is AIS, i.e. the content of
E1 data is all 1. Such alarm indicates fault conditions on the part of the downstream
equipment.
E1 LOS site is controlled by Dip Switch RA state. When RA Dip Switch ON, the
red LEDs indicate remote E1 LOS state. When RA Dip Switch OFF, the red LEDs
indicate local E1 LOS state.
