2. General Information
Overview
Thank you for selecting the RLH 16 Channel T1/E1 over IP/Ethernet multiplexer. This modular
multiplexer unit can be used to provide T1/E1 communication channels over Ethernet or IP networks.
The RLH 16 Channel T1/E1 multiplexer has many optional parameters, that can be modified by the user
to suite different application requirements. Please read this guide carefully before installing the product.
It is well known that the T1/E1 signal comes from PCM technology which is TDM in nature. It transmits
information in a constant bit rate of E1 2048kbit/s, TDM technology occupies fixed transmission
bandwidth, with QoS features suitable for real-time applications such as voice and video. The QoS
features include short and stable transmission delay, low jitter and wander, etc.
On the other hand, Ethernet is based on statistical multiplexing, transmitting and exchanging information
in packets. It does not take up a fixed transmission bandwidth, which is good for achieving higher
bandwidth utilization. But Ethernet technology does not provide adequate QoS for real time applications.
Until recently, voice and data were, and still are to a large extent, transported over two separate
networks. But the requirement for both types of information to be carried over a unified network is
growing rapidly. Packets over SONET/SDH techniques to integrate data into the TDM network have
been around for many years. But for voice over packet based data networks, most of the efforts are
spent on creating special equipment that specifically packets voice or video signals, such as equipment
used for VoIP.
However, to take advantage of the data network, it is neither cost effective, nor necessary to replace all
TDM based equipment with new packet based equipment. The RLH 16 Channel T1/E1 Mux can be used
to emulate transparent T1/E1 channels over an Ethernet with adequate QoS, so that most existing T1/
E1 based applications can be readily setup over Ethernet LANs and WANs. One such application is to
build T1/E1 links with low cost wireless LAN bridges, replacing much more costly microwave radios.

Typical Application in a Wired Network
In the diagrams above, a pair of RLH-TG-2A-1 multiplexers create transparent E1/T1 channels over the
packet network, providing connections between the PBX and telephone exchange, or other terminal
devices. At the same time, computers talk to each other through the local Ethernet ports. This
configuration guarantees that the T1/E1 channels get higher priority over computer data for maximum
QoS.

General Information
The most widely used application of the RLH-TG multiplexers is to set up point to point wireless T1/E1
links using low cost wireless LAN bridges. RLH-TG multiplexers can work with most LAN bridges on the
market. It may be necessary to adjust different parameters such as packet size and packet jitter
absorption buffer size for best operation for different LAN bridges.
Be aware that wireless LAN bridges have a very limited bandwidth. If Ethernet data is to be transferred
at the same time, its traffic must be restricted. Otherwise it will affect the T1/E1 packets. Since the LAN
bridges usually don’t have adequate QoS mechanism to guarantee the T1/E1 priority, it is strongly
recommended that the data traffic be routed through the device’s local data port.
Warning
When connecting to a wireless LAN bridge, the uplink Ethernet cable often connects to the outdoor unit,
posing danger to lightning strikes that can seriously damage the equipment. To protect the equipment
as well as people, surge protection devices with good earth connection is strongly recommended. Poor
earth connection may also hinder the operation of the Ethernet port, causing severe packet losses.

Typical HVP Application
Network equipment in high voltage areas can be at risk due to Ground Potential Rise (GPR). In this
instance copper network cable referenced to a remote ground can become a path for high voltages
during a ground fault. Use of all-dielectric fiber optic cable instead of copper completely eliminates the
presence of a remote ground, which dramatically increases safety of personnel and reliability of
equipment. By utilizing GE fiber optic cable, the RLH-TG multiplexer provides absolute electrical
isolation between both ends of the network.
Copper twisted pair Ethernet is limited to 100m/328ft without extenders. Using fiber optic cable
provides long distance service up to 80km/50mi. without any additional equipment. Optical fiber is also
immune to EMI/RF interference, ground loops, and high voltage surges from lightning or ground faults,
and is ideal in electrically noisy environments such as near large power sources, electrical motors, and
radio communications equipment.

Note: 10/100Base-Tx interface has HP auto-MDIX function and it can check the transmission and
receiving sequence and make configuration. So both MDI and MDI-X interfaces are supported and both
cross line and direct line can be selected.
The Ethernet optical port uses an SFP optical transceiver. Different transceivers are available to suit
multimode, single mode, distance and fiber connector requirements. The input and output side of the
transceivers are marked on the transceiver itself. Refer to the Ordering Information section for
compatible transceivers available form RLH.
Power
Two power supplies are available, 115AC and 24~48VDC. There are two power supply slots on the
chassis, and power supplies may be used in any combination. The power supplies are redundant, with
automatic fall-over in the event one power supply fails or loses input. Power supply options are specified
during ordering, and spares are available. See the Specifications section and Ordering Information
section for additional information.

DC Power
Use the supplied DC power connector for the DC Power supply. Connect a local 24~48VDC power supply to
the power connector. Make sure that the wire terminals are securely tightened. The ground contact is a
chassis ground, and must be connected to prevent damage or injury during high voltage events.
The DC power supplies use a PPTC resettable fuse, no customer replacement is required.
Note: The power terminals are polarity sensitive. Attach the positive DC wire to the V+ terminal only.
AC Power
Connect a local 115~240VAC power supply to the power connector using the supplied AC power cord.
The outlet must be grounded for safe operation. Turn OFF the power switch on the power supply before
connecting or disconnecting the power.
Note that there is a 1A fuse in the AC socket which may be replaced when blown. Contact RLH for
replacement fuses.
On the left corner of rear panel, a screw is used for connecting the chassis to the protective ground. Be
sure to make this connection using a thick wire.
Warning: The system must be securely connected to a good protective ground for safety. All
interconnected equipment must be grounded for maintaining signal integrity as well. Ground potential
faults may also damage the interface ports.
E1/T1connections
The E1/T1 ports on RLH-TG Mux are used for connecting to T1/E1 equipment such as the telephone
exchange or PCM terminals.
Up to 16 E1/T1 ports are supported. T1/E1 port impedance are 120Ω for twisted pair cables or 75Ω for
coax. The T1/E1-120Ω RJ45 sockets are default for ports.
The T1/E1-120Ω connection cable is made with RJ45 connectors and a breakout cable that is supplied
with the unit. Refer to the RJ-45 T1/E1 pinout information in Section 3. Components.
When making up a cable assembly in the field, note that pin-1 and pin-2 should use the same twisted
pair, so should pin-4 and pin-5. T1/E1 service can set the actual service quantity by NMS, set the exact
T1/E1 channels received by local equipment from remote equipment, realizing T1/E1 service one point
to multi-point unidirectional transmission function.
By NMS, T1/E1ports provide local loop back and remote loop back, each set of 8 T1/E1 ports loopback
can be set independently, and by the DIP switch RA on front panel T1/E1 indicators can be controlled to
indicate local or remote ports LOS and AIS status. The local and remote loop back definition is shown in
the following diagram.

The Ethernet optical interface uses SFP integrated optical modules. Dual fiber transceivers are marked
with  for the optical signal input and with  for the optical signal output. When connecting optical

fiber to the transceiver, roll the fiber connections by attaching the Tx connector from on end to the Rx
connector on the far end. Single fiber bi-directional transceivers are provided in pairs identified as C side
or S side.
Keep the SFP protection plug and optical optical fiber caps in place until installed to prevent
contamination.
Note: Fiber cable should always be routed loosely avoiding tight bends. Patch cord bend radius should
be no less than 50mm. The optical connector should not be pulling directly on the transceiver.

5. Troubleshooting
This section describes common mistakes and faults that may occur during installation and maintenance.
E1/T1 Alarm LEDs on
There are two groups of LEDs, PKT LOS and LOS for T1/E1 alarms LEDs.
When T1/E1 LOS LED is on, loss of T1/E1 signal fault is detected by RLH-TG Mux. Possible causes
include:
•
The downstream equipment such as telephone exchange or PCM terminal is powered off.
•
The T1/E1 cable connection looses or broken.
E1/T1 LOS LED blinks when respective input T1/E1 signal is AIS, i.e. the content of T1/E1 data is all 1’s.
Such alarm indicates fault conditions on the part of the downstream equipment.
E1/T1 LOS site is controlled by Dip Switch RA state. When RA Dip Switch ON, the
red LEDs
indicate remote T1/E1 LOS state. When RA Dip Switch OFF, the red LEDs indicate local T1/E1 LOS
state.
The T1/E1 PKT LOS lights are packet loss indicator, On for Ethernet packet loss, Blink for T1/E1 Packet
Loss, Off for Normal.
Lnk/Act LED off
Lnk/Act LED off means the corresponding Ethernet link is not working. Check the Ethernet cable
connection, and the status of the device on the other end of the cable.
Ready LED does not blink
After power on, the Ready LED should start to blink. If not, try switching power ON and OFF. If this error
persists, call for support.
Cannot set up T1/E1channel
Same LAN domain
When two RLH-TG Mux’s are within the same Ethernet broadcast domain, try following.
20
•
Check if the transmission network is on.
•
Check that the network will pass broadcast packets. For a network that suppresses broadcast packets, as some
of the wireless LAN bridges do, disable ARP and manually setup local and remote MAC’s.
•
Check that there is no MAC address conflict on the LAN.
•
Check that the transmission network has enough bandwidth (more than 2.5Mbps duplex).
RLH Industries, Inc. - 16 Channel T1/E1 over GE with Fiber
Troubleshooting
Different LAN domain
When two RLH-TG Mux’s are in different Ethernet broadcast domains, IP headers must be used, and
packets will be routed by a gateway router, try following:
•
Check if the default gateway IP is defined correctly.
•
Check if the local and remote IP is set correctly.
•
Check for any conflicts in IP or MAC addresses.
•
Make sure the transmission network has enough bandwidth.
Downstream reporting slips
Check if the downstream equipment has correct clock mode. At least one of them must be clock
master. Set the RLH-TG Mux on master side to loop back timing.
If the downstream equipment on both sides is not synchronized, slips are not avoidable.
At the transition time after power on or reapplying the T1/E1signal, slips and errors are acceptable. Such
transition may take several minutes.
If trouble persists, replace the unit and retest. If technical assistance is required, contact the RLH
Industries, inc. technical support department:
800-877-1672 (6 am to 6 pm- PST),
or call our 24/7 Technical/Customer Service: (714) 366-2503 or (714) 457-5740

Service configuration indication
•
Bandwidth auto adaptation for E1/T1 depends on whether the connection of E1/T1 is enabled or disabled. It is
suggested to disable E1/T1 channels when they are not used.
•
The MAC address of RLH-TG Mux is fixed in the device. It is a unique, 12-hex MAC address, such as
80-80-80-80-80-80, that enables communication with other equipment. Since the RLH-TG Mux’s MAC address is
already fixed, there is not need to set it again. ARP is supported and the remote end MAC address can be
obtained through auto-negotiation. Therefore it is unnecessary to set the MAC address for the remote end, but an
IP address is needed.
Note: Each device may have only one MAC address in the multicast zone
28
•
To improve the E1/T1 data transmission service quality, the Ethernet transmission supports IEEE 802.1Q and
802.1p QoS standards. The RLH-TG Mux can set to add a VLAN tag with priority in the packet encapsulation
process. According to 802.1Q/802.1p standards, the encapsulation overhead is bigger (4 bits are added in each
Ethernet packet), but it also can be transmitted according to the priority level. If the network doesn’t require
802.1p, there is no reason to set VLAN because it will increase bandwidth usage. In this case set VLAN to Disable.
•
In order to avoid a management failure caused by configuring VLAN, do not set VLAN tag for the managed VLAN
members (select off untag). Deselect internal trunk also. If internal trunk tag is needed, use the “remote first” rule
and configure the remote equipment VLAN table first, then configure the VLAN table for the equipment connected
using the management PC. If management failure is caused by configuring VLAN, set DIP switch 3 to OFF, which
will disable VLAN.
