2 Alcatel -Lucent 7670 RSP ESC

K E Y F E A T U R E S

The ESC supports:

Eight OC-3/STM-1 ports, with

channelization down to DS1/E1 level

Two OC-12/STM-4 ports, with

channelization down to DS1/E1 level

ATM, IMA andCE

672 DS1s and 336 IMA groups on a

single card (SONET variant, OC-3 card)

504 E1s and 336 IMA groups on a

single card (SDH variant, STM-1 card)

The ESCdelivers industry-leading scalabil-

ity of more than 16,000 DS1s/12,000 E1s

per 7670 RSP system.

In conjunction with the Alcatel-Lucent

7670 R

SPs har

dware an

dcontrol re

dun-

dancy and high availability features

(non-stop signaling, routing and

forwarding), the ESC offers superior

carrier-grade protection capabilities:

Physical line protection, in the form of

automatic protection switching (APS)

Line card protection, in the form of

equipment protection switching (EPS)

Unique service-level protection in

the form of stateful, non-stop IMA

The ESC is fully managed by theindustry-leading Alcatel-Lucent 5620

NM, which addresses key operational

requirements for mobile operators:

Point-and-click GUI, with end-to-end

management and provisioning

Easy assignment of Node Bs to RNCs

and Node Bs re-parenting

Flexible configuration and

reconfiguration

Alarm reporting

Remote diagnostics andtroubleshooting

Real-time statistics collection

and reporting

Full redundancy

Integration to OSS/BSS systems

(CORBA/CMIP)

The ESC minimizes the technological

risks by allowing smooth evolution to

future functionality (such as MC/ML-

PPP) via software upgrades.

The multiprotocol features of the

Alcatel-Lucent 7670 RSP allow

simultaneous support of cell relay,

Ethernet, IP/MPLS andCE.

3Alcatel-Lucent 7670 RSP ESC

In this scenario, the Alcatel-Lucent

7670 RSP is located in the MTSO, where

it aggregates Iub traffic from a large

number of Node Bs and provides con-

nectivity to the RNCs. The excellent

traffic management and quality of

service (QoS) capabilities of the 7670 RSP

allow managed growth of bandwidth-

intensive 3G and HSPA traffic.

In scenarios where the centralized

aggregation of mobile traffic needs to

encompass more than six to eight STM-

1s/OC-3s, the deployment of the 7670

RSP and the ESC provides tangible

and measurable benefits over similar

solutions with lower port densities and

capacities. The 7670 RSP provides the

highest port density and highest capa-

city in the industry for the mobile back-

haul and aggregation. Augmenting the

7670 RSPs high-capacity aggregation

role with further optimization of band-

width utilization of interfaces towards

RNCs (Iub and Iur) can result in combined

savings of up to 25 percent on trans-

port costs and RNC interfaces over

non-optimized scenarios.1

Figure 1 shows one such example

of centralized, high-capacity mobile

aggregation. The 7670 RSP and its ESCs

are used to terminate virtual paths

from a large number of Node Bs and

deliver the traffic to adjacent RNCs

via a smaller number of bandwidth-

optimized interfaces. In addition, the

7670 RSP is used to optimize connec-

tivity towards the PSTN, SGSN and

towards the mobile core network.

Combined 3G Aggregationand 2G Switching at the MTSO

The ESC is also instrumental in

enabling cost-effective converged

transport infrastructure for 3G and

2G mobile traffic. (Figure 2)

With the ability to perform TDM

switching (CE) on the ESC, the role of

the 7670 RSP in the MTSO can extend

to providing connectivity not only to

RNCs, but also to legacy 2G BSCs and

mobile switching centers (MSCs). By

doing so, a mobile operator can reduce

the number of networking elements in

the MTSO and increase overall

reliability and availability. (Figure 3)

Fixed and Mobile Applications

The ESC can also be deployed as a high

density card for other ATM, IMA and

CE applications for fixed and mobile

operators.
