ACE-3402 Cellular Backhaul Aggregation Unit DESCRIPTION • ACE-3402 delivers TDM and
ATM-based virtual containers in a channelized STM-1/OC-3 over ATM STM-1/OC-3c or packet-switched networks (PSNs), such as Ethernet, MPLS or IP.
• As a multiservice aggregation unit, ACE-3402 aggregates and optimizes multiple traffic types in 2G and 3G cellular backhaul applications.
ATM TRAFFIC
• The unit supports up to 1024
ATM connections with full UNI VPI and VCI ranges.
• Using ACE-3402, operators can
assign each virtual connection (VC) or virtual path (VP) to a service class, define the QoS parameters and shape the ATM egress traffic accordingly. This assures QoS in delay-sensitive applications.
• ACE-3402 provides traffic
scheduling according to CBR, VBR, UBR and UBR+.
• Rate limiting can be applied to each STM-1/OC-3c port.
• Inverse multiplexing over ATM
• The encapsulation of TDM traffic
ATM over PACKET
CHANNELIZED STM-1/OC-3
• ACE-3402 utilizes up to
• When equipped with channelized
(IMA) version 1.0 and 1.1 is supported.
512 pseudowire connections to emulate 3G ATM services over packet-switched networks .
• The following encapsulation
methods are supported according to draft-ietf-pwe3-atm-encap: 1:1 VC/VP – Each VCC/VPC is mapped to a single pseudowire (PW) connection N:1 VC/VP – Several VCs or VPs can be encapsulated to a single PW connection.
• ACE-3402 allows single or
multiple cells to be encapsulated per frame.
TDM over PACKET
• ACE-3402 allows 2G cellular traffic to be carried over packet-switched networks.
• To compensate for the jitter
caused by the packet-switched network, each TDM stream has a jitter buffer of up to 32 milliseconds.
APPLICATIONS
Figure 1. Hybrid Backhaul Solution
complies with ietf-pwe3-satop and ietf-pwe3-cesopsn requirements.
STM-1/OC-3 modules, ACE-3402 allows up to 63 VC-12 circuits (SDH) or up to 84 VT1.5 (SONET) circuits to be transmitted over a single STM-1/OC-3 UNI uplink or over a packet-switched network uplink.
• Each VC-12 or VT1.5 circuit can be channelized in UNI, CES or IMA mode.
• ACE-3402 allows CES bundles to
be transported over VC-12/VT1.5 traffic, with up to 8 bundles per port or 128/300 bundles in total.
QUALITY of SERVICE (QoS)
• Over packet-switched networks,
QoS is provided according to the network type: L2 network – outgoing pseudowire packets are assigned a dedicated VLAN ID according to 802.1Q and marked for priority using 802.1p bits MPLS network – outgoing pseudowire packets are assigned to a specific MPLS tunnel and marked for priority using EXP bits
IP network – outgoing pseudowire packets are marked for priority using ToS or DSCP bits. SYSTEM TIMING
• ACE-3402 provides a high
accuracy clock and flexible timing modes. The following transmit timing modes are supported for its STM-1/OC-3c interfaces: Loopback – derived from the receive clock of the current interface Reference – derived from the receive clock of the dedicated station clock port or any of the STM-1/OC-3c UNI or channelized STM-1/OC-3 ports.
• Over the packet-switched
network, ACE-3402 supports two timing options: Unicast clock distribution – the master clock is distributed with a dedicated stream towards up to 256 remote devices Multicast clock distribution – The master clock is distributed towards the PSN using a single IP multicast clock stream (IGMPv2 host).
STM-1/OC-3c/OC-3 INTERFACE
MANAGEMENT
• ACE-3402 features up to two
• ACE-3402 can be managed using
STM-1/OC-3c UNI interfaces, and up to two channelized STM-1/OC-3 interfaces: The STM-1/OC-3c UNI interface performs physical layer and ATM mapping into STM-1/OC-3c according to ITU I.432. The SDH or SONET operation mode is user-selectable. The channelized STM-1/OC-3 interface provides 63 VC-12 or 84 VT1.5 channels. Each channel can be set to ATM UNI/IMA or TDM mode.
• Automatic Protection Switching (APS) is supported by both interface types, to ensure a fail-safe, continuous operation.
GIGABIT ETHERNET INTERFACE
• ACE-3402 includes one
Gigabit Ethernet interface module, which supports fiber optic Small Form-Factor Pluggable (SFP) transceivers. Electrical 1000BaseT interface is also supported. • The Gigabit Ethernet interface is used for uplink connection and inband management access.
• The unit supports standard IP
different access methods, via: Dedicated RS-232 or 10/100BaseT ports Dedicated ATM VC defined on an STM-1/OC-3c ATM port Gigabit Ethernet uplink port (inband management). • The unit can be managed by and report to up to 16 different managers simultaneously. This enables viewing the network status from different locations.
• The following applications can be
used for management: Menu-driven terminal utility via an ASCII terminal connection Telnet via an IP-based connection ConfiguRAD, Web-based element management tool via an IP-based connection RADview-Lite, RAD’s SNMP-based management access system.
• Software upgrades and
configuration files can be downloaded/uploaded to/from ACE-3402 via TFTP or XMODEM.

ACE-3402 Cellular Backhaul Aggregation Unit OAM and DIAGNOSTICS
• Comprehensive monitoring and
diagnostic capabilities include: Pseudowire connectivity check External and internal physical loopbacks on STM-1/OC-3c ports Cell test towards the ATM connections.
• For ATM cross-connects (XCs),
OAM is supported according to ITU I.610 requirements: F4 and F5 OAM support Configurable OAM mode per connection point Segment/intermediate mode for user connections and end-to-end mode for the management connection AIS and RDI cell detection and generation upon physical layer and ATM layer failures CC cell generation and LOC state detection per VP/VC Loopback location ID and configurable loopback source ID per device.
• The connectivity status of
pseudowire connections is verified periodically by ACE-3402 using a VCCV-BFD according to the draft-ietf-bfd-base requirements. If a failure is detected, a notification is sent to both the remote peer and the ATM/TDM connection of the specific PW. This allows complete monitoring over the PSN pseudowires in real-time.
• ATM or TDM alarms are
forwarded over the packet-switched network to the management station. This includes the mapping of: Packet-switched network alarms to ATM/TDM alarms ATM/TDM alarms over the PSN to the remote CE Physical failures of ATM/TDM ports, over the packet-switched network towards both the local CE and the remote CE.
• Performance monitoring is
• ACE-3402 collects statistics per
physical port and per VCC for 15-minute intervals. Statistics for the last 6 hours are stored in the device and can be retrieved at the network management station.
• For diagnostics purposes,
ACE-3402 maintains a cyclic event log file that stores up to 4096 time-stamped events.
MODULAR ARCHITECHTURE
• The modular architecture of
ACE-3402 allows hot-swappable modules to be replaced in the field while maintaining uninterrupted service. The unit is also fully accessible from the front panel.
• The unit's full hardware
redundancy features (fans, power supplies, modules) ensure a fail-safe, continuous operation, making ACE-3402 ideal for carriers and service providers.
provided by Ethernet and IP-layer network condition statistics, such as packet sequence errors (loss or misorder) and packet delay variation (jitter), which are monitored and stored by the device.
