Optimux-XLE1 Installation and Operation Manual Chapter 1 Introduction

Features

Optimux-XLE1 is a compact 44 mm (1U) high unit intended for 19-inch rackinstallations using an adapter kit.

Optimux-XLE1 integrates multiple E1, Ethernet, Fast Ethernet and High Speed datalinks and enables E3 transmission over a coax, dual fiber or single fiber over a

range up to 110 km (68 miles).

Optimux-XLE1 is a modular optical multiplexer which enables to mix and match awide variety of interface options. Each Optimux-XLE1 is equipped with four I/Oport modules. One of these port modules contains a single 10BaseT Ethernet port.The other three port modules can either be other Ethernet ports, or any one ofother available options. A variety of different interface types can be combined intoa vast array of port options. The various types of interface options include:

10BaseT Ethernet

Fast Ethernet

E1

HS (High Speed channels)

HSSI

N64 kbps channels

Various possible combinations of tributary ports can be combined into a single E3link. Optimux-XLE1 is suitable for coaxial cable unbalanced E3, and severaldifferent modes of fiber optic transmission.

Optimux-XLE1 features link redundancy (an optional backup link), which enablescoupling of any combination of fiber and coax modules to the link, and providesan automatic backup, should one of the E3 links fail. In addition, Optimux-XLE1

can accommodate up to two built-in power supplies. The power supplies can beeither AC-to-DC or DC-to-DC, and are available in a wide range of power sourcelevels. The optional, second power supply within the same Optimux unit enablesredundancy in case of power failure or disconnection.

Optimux-XLE1 offers the options of working in internal, loopback timing orexternal clock. The external clock option is provided by an available (optional)station clock module.

Setup, monitoring and diagnostics can be configured using an ASCII terminal,Telnet or an SNMP management station. System diagnostics are monitored andmanaged using status and alarm panel indications, alarm dry contacts and external

management tools.Optimux-XLE1 conforms to ITU G.703, G.742, G.751, G.823 and G.956.

1.3 Functional Description

E3 Link Interface

Optimux-XLE1 can be ordered with an E3 electrical or a fiber optic link interface.

The electrical interface provides short-range transmission according to ITU-TG.703 via the coaxial cable infrastructure. The optical interface is used to extendthe transmission range to 110 km (68 miles), enhance transmission security andachieve immunity against electrical interference.

Link Redundancy

An additional link interface can be ordered for backup. The two link interfacesmust be either both electrical or both fiber optic. If they are fiber optic, they canbe of different types. The link interfaces are implemented by interchangeable linkmodules plugged into two dedicated slots at the rear of the Optimux-XLE1 unit,designated LINK A and LINK B. Front panel LEDs provide AIS and signal loss

(SYNC LOSS) indications on the link.

When two link modules are installed, the redundancy mechanism of theOptimux-XLE1 is used to:

Automatically switch to the backup link interface in case of signal or sync losson the main link. If the redundancy mode is set to AUTOMATIC, under signalloss, the main link (equipment and/or line) resumes transmission after it hasrecovered. Under sync loss, the backup link continues transmission until itreceives a sync loss/signal loss.

Force transmission via one of the links using a software management tool formaintenance purposes if the redundancy mode is OFF.

When the redundancy mode is MANUAL and the main link is disconnected orfails, the backup link is forced into the active state. The main link will not resumetransmission as long as the redundancy mode is MANUAL.

In addition, any of the Optimux-XLE1 fiber optic links can be configured as themain link.

E3 Electrical Interface

The electrical interface complies with the ITU-T Rec. G.703 for E3 75 unbalancednetwork termination. Four Ethernet channels or one Ethernet channel and E1, Fast

Ethernet, HSSI, N64 and High Speed channels are combined into a 34 Mbps

data stream in the upstream direction (towards the link). In the downstreamdirection, the E3 data stream is split back to Ethernet, E1, Fast Ethernet, HSSI,

N64 and High Speed channels. The HDB-3 line coded bipolar 1V signals areapplied to the link via two BNC connectors (transmit and receive).

It is possible to add a redundant electrical link to an existing unit or to replace thelink module by the E3 coax AMC-101 module.

Functional Description 1-5

8/22/2019 OP_xle1

18/92


E3 Fiber Optic Interface

The E3 fiber optic interface complies with the ITU-T Rec. G.652, while applying aproprietary signaling format to the NRZ 34 Mbps data stream. In the upstreamdirection, the data stream modulates the beam emitted by the optical device,either an LED or a laser diode. In the downstream direction, the data stream is

recovered from the current changes in a diode sensitive to the received opticalbeam.

Various optical interfaces meet a range of customer and infrastructure needs.Table 1-1 shows the Optimux-XLE1 options in terms of transceiver, fiber optic andmaximum transmission range. The maximum transmission range is a function ofthe optical budget (transmitter power minus receiver sensitivity), the fiber opticattenuation per kilometer and the necessary margin due to CO connections, aging,etc. In Table 1-1 a typical 3 dB margin has been assumed to calculate themaximum range. Front panel LEDs indicate loss-of-signal frame and AIS on thelink.

It is possible to add a redundant fiber optic link to an existing unit. It is alsopossible to replace the link module with the 850 nm multimode AMC-101 moduleor with any one of the single mode AMC-101 modules. Regardless of the type oflink selected, Link A and Link B must be of identical type.

A selection of Ethernet, Fast Ethernet, E1, High Speed and HSSI channel modulespermits a variety of multiplexing schemes for LAN and CO sites. The Ethernet orFast Ethernet ports are connected directly to the local network or to an EthernetLAN. The port activity and the link integrity are monitored either by front panelLEDs or by an external terminal. The transmission of the Ethernet or Fast Ethernetchannel is implemented by a built-in bridging function operating at the8.448 Mbps, "almost wire-speed", rate and supports up to 10,000 (Ethernet) or16,0000 (Fast Ethernet) addresses.

The E1 interfaces, both balanced and unbalanced, comply with the ITU-T Rec.

G.703. Line coding is HDB-3 or AMI. Balanced transmit levels are nominally 3V

for balanced termination and 2.37V for unbalanced termination. A pair of LEDsmonitor loss-of-signal and AIS on each E1 receive line.

For the High Speed and N64 modules (V.35, RS-530 and X.21), the desiredphysical port connector is achieved by the use of an appropriate adapter cablewhich is supplied with the product.

Note

When using one of the 1HS/8M type interfaces, the received clock arrives from theE3 to the E2 demultiplexing, which generates a gapped clock at E2. Therefore, theequipment connected to this port should be able to receive a gapped clock.

Management Requirements

Optimux-XLE1 operates locally using on-board switches and jumpers to configurethe operation modes; and front panel LEDs to monitor system failure and tests(loop connections). Alarms are monitored using the dry contacts of theOptimux-XLE1 alarm relays on a dedicated D-type connector.

A V.24/RS-232 port enables monitoring and tests using an ASCII supervisionterminal.

The management interface also includes an SNMP agent that enables SNMPmanagement of the Optimux-XLE1, using the Ethernet protocol. The SNMPmanagement capability enables fully graphical, user-friendly management usingthe RADview network management stations offered by RAD, as well asmanagement by other SNMP-based management systems.

Remote management is also possible using the Telnet communication protocol,which uses TCP/IP communication, without the SNMP service. Telnet supportenables a remote IP host to control the operation of Optimux-XLE1 using functionsidentical to those provided by a supervision terminal. The Telnet management

function can be protected by the manager password feature.

Note When using Telnet for management, the Software Downloading option is notoperational.

Timing

Optimux-XLE1 (E3)

Optimux-XLE1 can work with an internally generated clock (internal oscillator).

Loopback timing can be used in those systems that require a one-source clock.

There is an option to work with EXT clock for systems that require this feature. A2.048 MHz AMI or square signal with 10 PPM accuracy is applied to the stationclock module and the module converts it to the 34.368 MHz clock for theOptimux-XLE1. A 2.048 MHz signal is available on the station clock moduleoutput in AMI code for other systems in use.

Only one station clock module is necessary for a pair of Optimux-XLE1s workingopposite each other. The Optimux-XLE1 device that has the station clock moduleworks in EXT clock mode, while the other works in loopback timing mode.

When working in EXT clock mode, redundancy on the network link is not possiblebecause the station clock module occupies one of the network link slots. If

working with EXT clock, in addition to Optimux-XLE1, order the station clockmodule (see the Optimux-XLE1data sheet for ordering options).

HSSI Interface

The HSSI module supports internal timing mode only (see Figure 1-4). This means,the Optimux-XLE1 always provides the clock source.

In internal timing mode, the Optimux-XLE1s internal oscillator supplies the clockto the DTE for the data transmit.

4HSx2M internal, external and loopback timing

1HSx8M internal and external.

NoteAlthough the X.21 interface does not support the external clock mode, High Speedmodules with X.21 interface operate in EXTC mode by using pin 7 (EXTC A) andpin 14 (EXTC B).

Figure 1-10. Timing Modes for V.35/RS-530/X.21 Ports of the N64 Modules

To ensure proper operation, one of the N64 modules must be set to the internal

or external clock. The opposite N64 module must be configured to the loopbacktiming.

When configured to the external clock, Optimux-XLE1 automatically detects the

DTE baud rate and configures the N64 accordingly.

Although the X.21 interface does not support the external clock mode, the N64modules with X.21 interface operate in EXTC mode by using pin 7 (EXTC A) andpin 14 (EXTC B).

Note

HSSI Interface Control Signals

According to HSSI standards, the following control signals are supported:

TA (Terminal Available): the DTE asserts this signal when ready to receive andtransmit data.

CA (Communication equipment Available): the DCE asserts this signal whenready to receive and transmit data.

TM (Test Mode): the DCE asserts this signal when the DCE is in a test modecaused by either the local or remote DCE.

Power Requirements

Optimux-XLE1 can be connected to 115 VAC or 220 VAC mains, or to a batterysource supplying 48 VDC or 24 VDC.

A second optional power supply can be installed in the Optimux-XLE1 to assurecontinuous operation in case of power supply failure. When the two supplies areturned ON, they share the load of the units power consumption. If one of thepower supplies fails, the other one provides full power output for the unit.

Channel Connections

The Optimux-XLE1 has four groups of interface ports designated A to D on thefront panel of the unit.

Channel A is a fixed 10BaseT Ethernet port with an RJ-45 connector. The othergroups of interface ports should be prepared according to the ordered channelmodules (see Table 1-2. Channel Module Options). Any combination of 10BaseTEthernet, E1 balanced, E1 unbalanced, Fast Ethernet, High Speed and HSSImodules can be installed in Optimux-XLE1 slots B to D (see Figure 2-1. Location of

Modules in the Optimux-XLE1 Case). A vacant slot should be closed up using ablank panel.

For E1 lines, the maximum allowable line attenuation between the E1 ports andthe user's equipment is 6 dB according to ITU-T G.703. The cable type and lengthshould be selected accordingly. The length of a standard UTP cable to a 10BaseTEthernet or 10/100BaseT station is 100 meters (330 ft).

Station Clock

One link is provided according to order. The module must be installed on link B.The station clock module is provided with a pair of BNC connectors. One Squareor AMI connector is used for the 2.048 MHz input signal (10 ppm accuracy). Themodule generates the 34.368 MHz from this signal. The other connector has an

output of 2.048 MHz signal AMI coded for use in other systems.Before connecting the station clock, you must install the station clock board.

To install a station clock board:

1. Slide the board into the LINK B location in the rear panel of Optimux-XLE1until it clicks into place.

2. Secure the board to the rear panel by fastening the two screws provided onthe board.

Refer to Table 2-2 for jumper settings of the station clock module.

Power Connection

The Optimux-XLE1 chassis ground is connected to the protective ground (middle)pin of the power connectors, both for the AC and DC versions of the unit.

Intentional disconnection of the protective ground is prohibited since such anaction may expose personnel to electrical shock hazards.

Before switching on or connecting any cable, the protective ground terminal(see Figure 2-1) must be connected to the protective ground connector of thepower cord. The power plug shall only be inserted in a socket outlet providedwith a protective ground contact. The protective action must not be negated by
