1 System Overview

1 System Overview

1.1 General

Tellabs 8600 managed edge system is a managed MPLS access solution aimed at deploymentof mobile transport networks, and Ethernet and IP VPN services as well as broadband serviceaggregation for Internet services. The system is especially designed for the service providerenvironment with carrier class functionality, simultaneously supporting both connection-oriented(MPLS) and connectionless (IP) operations. The use of IP/MPLS technology with enhanced qualityof service features enables differentiated services in which the service quality can be predefinedfor all traffic types and the availability of service can be protected with options built into thesystem. The quality of service is guaranteed with DiffServ and DiffServ-aware MPLS trafficengineering already in the access part of the network. The service speeds are flexible ranging from1 kbps to 1 Gbps. The connectivity services such as intranet, extranet, Internet access and voicecommunications are implemented as Ethernet PWE3 or IP VPN according to [RFC2547bis].

The boundary between mobile and wireline services and networks is disappearing. From the costpoint of view it makes sense to use the same network for all services. Tellabs 8600 platform hasa native support for services such as any-to-any IP VPN, Ethernet and ATM, all of which can beend-to-end provisioned and managed. Additionally the same platform can take care of the Internettraffic aggregation, which is one of the most rapidly growing business in terms of bandwidth.

1.2 Tellabs 8600 in Managed RAN Transport Application

For the mobile radio access networks (RAN) Tellabs 8600 managed edge system offers the onlyfuture proof transport solution in the market that caters the whole network technology evolutionfrom TDM to ATM and eventually to an ‘all IP’ RAN phase. As shown in the figure below theplatform is positioned to cover the whole transport network all the way from the cell sites to theedge of the mobile core. Throughout all the evolution phases traffic grooming, service qualityand transport can be managed and optimized end-to-end across the same Tellabs 8600 network.Even though 3G is the primary driver to implement the Tellabs 8600 system, the same platform –thanks to flexible MPLS technology and Tellabs 8600 intelligent design – can be responsible ofthe access aggregation for 2G and 2.5G networks and services. Tellabs 8600 platform offers aunique opportunity for a mobile operator to broaden the service portfolio and increase revenue byoffering advanced business or residential services, such as managed WiFi access, IP VPNs, businesscritical Ethernet or Internet access. Introducing services is extremely fast and cost-effective asall the service intelligence is in-built to the system. Tellabs 8600 system can be regarded as areal long term investment as it allows the network convergence already in the access, where thenetwork investments are the most remarkable.

1 System Overview

Fig. 1 Tellabs 8600 Position in RAN

Tellabs 8600 system is able to cover the whole RAN network from the cell site to the mobile core.The figure above illustrates the typical roles and locations of the elements in the network, which are

• RNC/BSC sites (Tellabs 8660 edge switch)

• Access aggregation, i.e. hub sites (Tellabs 8620 access switch, Tellabs 8630 access switch, andTellabs 8660 edge switch)

• Cell or base station sites (Tellabs 8620 access switch)

• MPLS-enabled multitechnology and service support

Tellabs 8600 system can simultaneously take care of mobile traffic aggregation of 2G, 2.5G and3G traffic even though they are based on various protocols. Flexible equipping and multiserviceinterfaces of Tellabs 8600 system enable building the network in the most economical way. Tellabs8600 system can optimize the bandwidth use in the network even by cross-connecting ATM VP/VCconnections. All the incoming traffic can be mapped to the needed traffic classes before it enters theMPLS network. Overbooking, which is essential for lower priority and bursty data services, can beused across the network. Finally, utilizing the MPLS PWE3 tunnelling ATM, TDM, and Ethernettraffic can be carried through the Tellabs 8600 network. Synchronization can be arranged to cellsites using various methods from SONET/SDH to packet synchronization.

2.1.1 Baseboard

Tellabs 8620 access switch is a stand alone device and uses a baseboard architecture. This meansthat the functionality has been integrated into a single main baseboard. Thus, there are no separateline cards. Interfaces locate on modules and are front access type.

2.1.2 Interface Module Slots

There are 2 slots, M0 and M1 for interface modules (IFMs). The operator can choose the media typeaccording to his needs. IFMs are not of hot-insert type.

2.1.3 Cooling

The main cooling method is convection. Fresh air is taken from the left side of the enclosure andblown through the board and module assembly. Outlet air leaves the enclosure on the right handside. Forced cooling is needed to dissipate generated heat load and to maintain components withintheir operating limits.

The fan module, located on the left hand side, contains three parallel fans. The baseboard is able tocontrol and monitor the operation of the fans. Rotation speed is adjusted according to temperatureinside the enclosure, and in case of failure in one fan, the other two will maintain adequate coolingfor a limited time.


20


The air filter is located in front of the fan modules. It prevents dust from entering the enclosure andkeeps IFMs clean in order to maintain normal convection efficiency. An empty IFM slot should beshielded with a cover plate.

The fan module and air filter can be replaced on the fly without disturbing data traffic through the NE.

The rotation speed control of fans is based on temperature values measured from the baseboard. Fanspeed is adjusted by three steps, 0%, 50%, 75% and 100% of the maximum rotation speed. In thenormal temperature range from -5° C to +45° C fans are running continuously. When the measuredvalue exceeds +67° C the fans speed up to maintain the required operating temperature. This willhappen at room ambient between +35° C and +40° C, depending on equipment furnishing andinstallation environment. The warning of high temperature occurs when the measured temperatureexceeds +81° C. This will happen in room ambient between +50° C and +55° C. If the warningoccurs and the equipment is not used in high ambient temperature, it may be advisable to changethe air filter.

The fans are shut down when the measured temperature value from baseboard is +15° C or below.They are started up again when the temperature reading is raised up to +58° C. This will happenin ambient -15° C or below. At start-up the fans are running until the equipment is booted up andable to monitor board temperatures.

2.2 NE Powering

In Tellabs 8620 access switch with AC power feed the AC mains input socket is on the backsideof the enclosure. A separate power module has an isolated AC/DC converter to create supplyvoltages needed to operate the NE.

Tellabs 8620 access switch with AC power feed must be connected to a wall socket-outletwith protective earth contact.

The DC power module consists of one fixed DC-DC converter card an two hot-pluggable powerinput modules which are front accessible.

AC and DC power feed features are the following:

• Over-current protection (fuse)

• EMI filtering

• Surge protection

• Hold-up time provider

Tellabs 8620 access switch must be disconnected from the mains supply before removing thecover as high voltages are present inside the case.


22


2.3 NE Synchronization

Tellabs 8620 access switch has an option for common timing generator. It is especially needed whenany SDH interface is in use. The generator locates on a Timing Module and the timing referencesignal is distributed to every IF on a NE via baseboard.

Timing Module provides an SDH equipment clock (SEC) complying with [G.813] Option 1 and[GR-1244-CORE] Stratum 3 generator. Typically it is synchronized with a clock derived fromany of the following input signals:

• n-port STM-n/OC-n IFM

• n-port E1/T1 IFM

• Station Clock Interface

• 2-port optical Gigabit Ethernet IFM

It is possible to configure the Station Clock Interface to G.703 2048 kHz synchronization clockmode, DS1 or E1 framing mode.

The selected reference signal must be originated from an equipment having at least the SEC qualityclock, for example, the reference signal quality must be as defined in [ETS 300 462-3] and [EN 300462-5-1]. This implies for instance that a 2048 kHz signal, which complies with [G.703] jitter andwander requirements, cannot necessarily be used as a reference.

Tellabs 8620 access switch can be equipped with one Timing Module. When it has been installed,the NE has one station clock interface, i.e. one input and one output port.

4 Power Modules

Tellabs 8620 access switch can optionally be powered with either AC or DC power supply. Theoperator is able to choose the needed module type according to his need.

4.1 AC Power Supply Module

4.1.1 Overview

Tellabs 8620 access switch has a separate power supply module with 90 - 264 Vac mains input. Itsupplies four output voltages (3.3V,5V,+/-12V) which are stabilized and galvanically isolated fromthe mains. The power supply has an active step-up type power factor correction which operatesas pre-regulator for the actual converter. The power supply module has a metallic top cover andinsulating bottom plate.

4.1.2 Interfaces

A mains input connector locates on the backside of the enclosure. There is no mains switch at all.The power supply input is protected against over-current with fuses. Those are on the primary side.

4.1.3 Operation

The mains voltage is fed through the input filter and fuses to the rectifier. The input filter alsoincludes the inrush current limiter and over voltage protection. The rectified voltage is fed to powerfactor correction circuit (PFC), which forms a 400 Vdc voltage for power stage converter (forwardtype). The pulse width modulation (PWM) circuit controls the power transistors and it protects theconverter from short circuits.

4.1.4 Technical Specifications

Power output Maximum 90 W

4 Power Modules

4.2 DC Power Modules

4.2.1 Overview

Tellabs 8620 access switch DC48 has a power supply module and slots for two power inputmodules on the front plate. The nominal input voltage is -48 Vdc. The power input modules havefilter and protection circuits and provide battery voltage to the power supply module. The powersupply module has two DC/DC converters, one for 3.3 V output and one for 5 V and 24 V output.Additionally there are +/-12 V auxiliary output voltages. All outputs are stabilized and galvanicallyisolated from the input.

4.2.2 Interfaces

Input connector, ON/OFF-switch and input fuse are located on the frontside of the power inputmodule. Output voltages 3.3 V, 5 V, +/-12 V and I2C-bus are connected from the power supplymodule to the basecard through the backplane board.

4.2.3 Operation

The input voltage is fed through the input filter and fuse to the input capacitors. The power inputmodule also includes the inrush current limiter for the capacitors and transient over-voltageprotection. Redundancy can be realized by using two power input modules in the enclosure. Thereis no active current sharing between the two power input modules. However, the current will benormally divided rather equally between the two power input modules. One power input module isable to supply the whole current to the Tellabs 8620 access switch when needed. All outputs ofthe power supply module have current limit circuits. The 24 Vdc output is for cooling fans. Thebasecard controls fan rotating speed via the I2C-bus and monitors the alarms. Fan driving circuitsare located on the power supply module.

4.2.4 LEDs

There is a LED on the front panel of the power input module to indicate the input voltage OK status.


Input Voltage OK GREEN ON when Input voltage is ONOFF otherwise.

5 Timing Module

5 Timing Module

The optional Timing Module is a Synchronous Equipment Clock (SEC) generator with a stationclock interface. Station clock interface supports E1 G.703 2048 kHz Synchronization Interface orinterface with Synchronization Status Messages. It is equipped on CDC or Tellabs 8620 accessswitch.

There are two Timing Module types:

• ETSI SEC Timing Module supporting only E1 G.703 2048 kHz Synchronization Interface

• ANSI Stratum-3 Timing Module supporting both E1 G.703 2048 kHz Synchronization Interfaceand E1 / T1 Synchronization Status Message Interface

The SDH synchronization function is specified in [EN 300 462-5-1] and [G.813]. The functionalmodelling is specified in [ETS 300 417-6-1] and [G.781]. STRATUM-3 generator is specified in[GR-253-CORE] and [GR-1244-CORE].

The module has the following main functional blocks:

• Temperature compensated SEC oscillator with PLL and holdover logic

• Station clock interface with PLL and Framer

• Reference clock selection logic

• Clock monitoring logic

The SEC clock is distributed via backplane to each card where an interface module with anSDH interface is able to use it as TX reference. In opposite direction, the recovered line clockcan be transferred to Timing Module and depending on configuration, SEC is able to use it as areference. Monitoring logic takes care that the selected reference clock is valid. It also monitors theoperation of both PLL and other available reference clocks set on the fallback list (contains clocksources/priority order selected by the user). If all the clock sources fail, SEC will enter into holdovermode and maintain frequency and phase drift within specified limits.

The station clock input/output interface is on the front plate of Timing Module. Depending onthe user needs, either coaxial or differential cabling can be used with a corresponding connector,i.e. SMB or D-sub.

Alarm RED ON when this physical interface detects an alarm (erroror other alarm, local or remote or loop_activated) that isremarkable enough to be indicated with a LED. Theremay be other alarms (typically of warning severity) thatare not indicated with an interface LED.OFF otherwise.BLINKING when manually set to do so.

OnLine GREEN ON when this physical interface is online (so it is“up” that means successful bootup sequence finishedand startup permission granted and not shut downadministratively). Note that online IF may still containerrors.BLINKING when manually set to do so.OFF otherwise, for example when in shutdown state.
