Figure 1-3. 2G/3G Aggregation over ATM
The following figure illustrates how ACE-3205 can be used to deliver HSDPA
traffic that is carried over DSL towards the operator’s site.

Features
Cellular Backhauling over DSL
ACE-3105, ACE-3205 uses DSL links as follows:
• For voice traffic (2G, RT99) backhauling – SHDSL links are used
•
For data traffic (HSDPA) backhauling – SHDSL or ADSL2+ links are used.
ACE-3105 aggregates data or voice traffic depending on its hardware
configuration (see
Figure 1-2
and
Figure 1-3
), while ACE-3205 aggregates both
data and voice traffic simultaneously using the SHDSL and ADSL2+ interfaces
together (see
Figure 1-1
).
ATM over PSN Capabilities
ACE-3105, ACE-3205 utilizes up to 32 pseudowire connections to emulate ATM
services over packet-switched networks.
Two encapsulation methods are supported according to IETF's
'draft-ietf-pwe3-atm-encap':
•
1:1 (one-to-one) VC/VP encapsulation – Each VCC/VPC is mapped to a single
pseudowire (PW) connection
