7705 SAR-8

The 7705 SAR-8 is a two-rack unit

(2 RU) version of the 7705 SAR with

industry-leading access density. The

platform can be optionally conﬁgured

with a redundant control and switch

module and uplinks. The Alcatel-

Lucent 7705 SAR-8 has eight slots;

two are allocated for control and

switch modules (CSMs), with the

remaining six being available for

user trafﬁc adapter cards. The Alcatel-

Lucent 7705 SAR-8 has a compact,

modular architecture, constructed

to allow ﬂexible use of line adapter

cards so operators can optimize the

conﬁguration to meet the speciﬁc

requirements of a site. With the

modular architecture comes additional

resilience and ﬂexibility. The platform

can optionally support 1+1 fully redun-

dant CSMs. This industry-leading,

independently validated High Avail-

ability feature has been inherited from

the Service Router product line and is

a strong contributor to overall network

uptime. Network uplink connectivity

options are: Ethernet, FE, GigE, n × T1/

E1 MLPPP or n × T1/E1 ATM IMA.

Integrated DS3 point-to-point trunking

is supported using the 4-port DS3

adapter card. OC-3/STM-1 trunking is

supported using Packet over SONET/

SDH (POS) on the 4-port OC-3/STM-1

clear channel adapter card.

7705 SAR-18

The 7705 SAR-18 is a 10 RU version of

the 7705 SAR with industry-leading

scalability. The platform can be

optionally conﬁgured with a redun-

dant control and switch module and

uplinks. The Alcatel-Lucent 7705 SAR-18

has 18 slots; two are allocated for

control and switch modules (CSMs),

with the remaining 16 being available

for user trafﬁc adapter cards. Twelve of

the adapter card slots have full duplex

2.5 Gb/s connectivity to the switching

fabric, the remaining four have full

duplex 10 Gb/s connectivity. The

platform can optionally support 1+1

fully redundant CSMs for High

Availability. The twelve 2.5 Gb/s

adapter card slots support the same

adapter cards as the 7705 SAR-8.

Network connectivity options are:

Ethernet, FE, GigE, n × T1/ E1 MLPPP

or n × T1/E1 ATM IMA. Integrated DS3

point-to-point trunking is supported

using the 4-port DS3 adapter card.

OC-3/STM-1 trunking is supported

using POS on the 4-port OC-3/STM-1

clear channel adapter card.

7705 SAR adapter cards

Each of the six adapter card slots in

the 7705 SAR-8 or the twelve 2.5 Gb/s

adapter card slots in the 7705 SAR-18, can

be used to house the following adapter

card types, this ﬂexibility alleviates the

burden of complex pre-engineering and

future scenario planning:
