ZXCTN 6000 Carrier-Class Multiservice

Transport Platform Intelligent Packet Transport Networks

Overview

Because of the growth of 3G/LTE services, bearer networks are required to provide multiple flexible functions with large bandwidth capacity and low cost. The ZXCTN 6000 product portfolio is committed to build a high efficient and power-saving wireless bearer network, and benefit telecom operators’ market extension & service innovation.

The ZXCTN 6000 supports Layer 2 networks, Layer 3 network, and service interworking reliably and concurrently. It enables service providers a graceful migration path to construct a converged packet transport network based on MPLS/MPLS-TP technology. It provides connection-oriented features of the traditional transport network such as SDH-like OAM, perfect protection mechanisms and powerful management, with the advantages of superior statistical multiplexing and flexible deployment of pure IP networks.

The ZXCTN 6000 offers a wide range of interfaces with unmatched service flexibility. It enables service providers the ability to deliver mobile backhaul services, business-class IP and carrier Ethernet services, Asynchronous Transfer Mode (ATM) and Time Division Multiplexing (TDM) private leased line services at speeds from E1 to STM-4, and Ethernet services from 10 Mbps to 10 Gbps.

Features

Any Service, Any Channel, Any Port

The ZXCTN 6000 can support Layer 1 to Layer 3

services on single platform with the flexibility of any

service, over any channel and any port with the

industry most comprehensive and flexible multi-

service interfaces supporting IP, MPLS, ATM, GFP, PPP,

TDM, pseudowire circuits and link aggregation. A

variety of line cards are implemented to support

packets, cells, TDM circuits, and the mixing and

matching of Fast & Gigabit Ethernet, optical &

electrical, and multi-rate SDH physical line modules.

Carrier-Class Reliability

The ZXCTN 6000 is a fully redundant platform to

provide carrier-class reliability. It offers a perfect end-

to-end protection mechanism for the services

transported. On the access side, the ZXCTN 6000

supports Link Aggregation Group (LAG), Virtual

Router Redundancy Protocol (VRRP), Inverse

Multiplexed ATM (IMA) E1 group and Linear Multiplex

Segment Protection (LMSP) for the access links. On

the network side, the ZXCTN 6000 offers multiples

network-level protections such as protection Linear

Protection, Ring Protection and FRR. Furthermore,

the ZXCTN 6000 provides Dual-homing protection to

enhance the networks reliability when failures

occurred at more than one point. On the equipment

side, hot standby redundancy for key components like

switching card and power unit are all supported. The

ZXCTN 6000 can offer best-in-class high availability

that is field-proven and time tested in more than a

dozen carrier networks worldwide.

New Generation Synchronization Technology

The cost-effectiveness and versatility of packet

transport networks are driving the convergence of

services. The transport of varies services leads to the

timing and synchronization requirements for the

packet network. The ZXCTN 6000 enables carriers to

provide SONET/SDH-like Layer 1 timing all over the

network via Synchronous Ethernet. The ZXCTN 6000

also supports IEEE 1588v2 time synchronization over

packet transport networks. Meanwhile, the ZXCTN

6000 provides IEEE 1588v2 Packet Timing Protocol to

distribute frequency information through mixed

networks and architect an LTE-ready network where

both frequency and phase synchronization are

required. As to the E1 circuit emulation services, the

ZXCTN 6000 can perform retiming, adaptive clock

recovery and differential clock recovery.

Special straturm-2 clock switch control cards are

provided for ZXCTN 6000, which can offer a high-

precision clock source to support the 3rd

party

network synchronization scenario.

Flexible Interwork Solution Scenario

At aggregation layer, the ZXCTN 6200/6220/6300

supports multiple gateway interworking boards,

including ch.STM-1/4, GFP POS STM-1/4, PPP POS

STM-1/4, SDH Gateway STM-1/4, CEP STM-1, ATM

STM-1, GRE, etc. It can provide integrated network

interworking solution, and fully satisfy the

requirement of complex network scenarios in access

layer, such as interworking with SDH equipments or

routers.

Special SDH gateway cards are provided by the ZXCTN

6000, which can support OAM, NMS and clock

synchronization information exchange between SDH

and MPLS-TP networks or between SDH and IP/MPLS

networks. As a result, the seamless connection

between SDH and packet networks can be achieved.

Carrier-Class OAM

The ZXCTN 6000 supports a rich set of OAM features

defined in the latest versions of IEEE, ITU and IETF

standards, including:

IEEE 802.3ah

IEEE 802.1ag/ITU-T Y.1731

Draft-bhh-mpls-tp-oam-y1731-04

LSP/PW Ping/Trace, VRF Ping/Trace

BFD

These capabilities enable the ZXCTN 6000 to monitor

the status of system and network links, measure the

performance of customer services, and confirm the

service throughput and quality according to SLAs.

Convenient Network Management

The ZXCTN 6000 can be managed by using ZTE’s

Unified Management Platform NetNumen™ U31,

which offers Graphical User Interface and provides

full operation ability including fault management,

topology management, performance management,

configuration management, security management,

log management, maintenance management and

various statistics reports. Meanwhile, the ZXCTN 6000

can also be managed and configured through

Command Line Interface (CLI), offering diverse

management options for different users.

Furthermore, once ZXCTN 6000 is powered on, it can

automatically communicate with the remote network

management system, and can be configured by the

remote NMS to achieve the easy featuring

commissioning and service deployment. The

NetNumen™ U31 supports intelligent tools as follows.

Automatic service cut-over tool

Intelligence network expansion tool

Batch update

Professional optical power management

subsystem

Long-distance Transmission

Usually, the long-distance transmission is utilized by

using WDM. But in some scenarios, the distance

between two network elements is beyond 80 km and

there is no WDM device available in the same site.

The ZXCTN 6200/6220/6300 solves this problem by

integrating optical amplification (OA) function on the

same shelf, and the embedded OA board can be used

as optical booster amplifier and/or optical

preamplifier with different power gains to enhance

the transmission distance to much more than 80 km.

Customer Benefits

Evolutionary Migration of Legacy

Networks

The ZXCTN 6000 supports open, standards-based

software and hardware to interface with legacy

equipment and protocols. Deployed legacy

multiservice networks can be integrated with the

ZXCTN 6000-based network as part of a non-

disruptive migration.

Guaranteed Service Availability

The perfect reliability mechanisms and redundant

hardware assures no single point of failure, non-

service affecting product upgrades, Layer 2 and Layer

3 protocol GR, in-service network expansion, carrier-

class protection and switching to maximize fault

tolerance and performance. Carrier-class design

provides full redundancy for common components

and software resiliency features enable maximum

service and networks availability.

Investment Protection

While increasing the breadth of the service portfolio,

the ZXCTN 6000 extends service providers’

investment in packet network equipment by scaling

its capacity as customer demands grow, without

forklift upgrades. With significant high-density and

high-speed capabilities, the ZXCTN 6000

accommodates growth in both end-user traffic and

services.

Capex Reduction

Service providers frequently maintain multiple core

service networks based on the individual end-

customer services being offered. The ZXCTN 6000

provides a consolidated network infrastructure

integrating multiple overlay networks to reduce the

total number of network elements. Capital

expenditures are further reduced with industry-

leading technology, port-density and performance

improvement.

Opex Reduction

The ZXCTN 6000 reduces truck rolls, lowers spares

inventory and minimizes operational costs for service

providers.

Low power consumption mechanism is

employed and the maximum power

consumption is less than 300 Watts which saves

a large sum of money for service providers.

Software-defined E1 card enables one single

card to access services of TDM, ATM and MLPPP.

Meanwhile one single Ethernet card supports

both FE and GE speeds.

In addition, the Graphic network management and

E2E service configuration further reduces operational

complexity of managing multiple networks or

network layers in the service provider network.

Reduced operations costs are facilitated to bring

greater profits and revenues.
