Benefits:

• GigE connectivity over multiple bonded DS3/E3 lines.
• Packet order maintained.
• Simply insert/remove TDM cards to arrive at desired bandwidth.
• Fine-grained per-packet load balancing eliminates single-user/single-link limitations.
• Automatic selection of lowest-latency available link for every packet.
• An alternative to coarse-grained DS3-capable router and DS3-network interface card.
• Cheaper than typical DS3 capable routers.
• Simple, GUI configuration.
• Saves router bandwidth.
• Comprehensive, user-friendly-HTTP and SNMP management.
• Rack-mount chassis available from single-card through 20-cards.
• Jumbo-frame and SFP-optical port LAN flexibility.
• Rx-to-Tx 100% packet tracking/auditing stats.
• Fanless or dual-power reliability.
• Enhanced WAN frame-lock algorithms for higher bit-error-rate environments.

Product Summary:

Providing Ethernet connectivity over multiple DS3/E3 circuits, the E3Switch GigE LAN to WAN switch provides a simple, inexpensive alternative to the inefficient load-balancing of DS3-capable routers and DS3-network interface cards.

Per-packet load balancing - choosing lowest-latency available link first - allows for maximum WAN bandwidth utilization. Failing links are automatically removed from service.

Simply insert or remove TDM cards or connections to adjust from 44 Mb/s up to full GigE bandwidth desired

Fanless operation and low part-count design allows use with greater reliability and in harsher environments. NEBS Level 3 multicard, redundant-power chassis are available.

9700-byte jumbo packets and on-board SFP port allows flexibility.

Management functions include both comprehensive SNMP statistics with link up/down and DS3 FEAC notifications as well as one-click HTTP, user-friendly, color-coded monitoring of link operational status and bit-error rate. Unique packet auditing display allows individual tracking of every packet from ingress to disposition/egress -- never lose another packet.

Robust, WAN frame-lock algorithms maintain link stability and high-BER tolerance on noisy paths such as multi-hop microwave.

Requirements:

• Clear-channel TDM DS3/E3 links required.

Detailed Capabilities:

Power/Mounting:

• AC or DC -- 100-240 VAC or +/- 35-75 VDC.
• Rackmount, multi-card or tabletop chassis available.
• Redundant-power chassis available.

VoIP:

• VoIP ready with dedicated QOS queues.
• Ultra-low latency packet forwarding.

Packet-size:

• GbE jumbo frames supported to 9700 bytes.

Date Rate:

• TDM Bit-rate: 44.736 Mbit/s DS3 -- 34.368 Mbit/s E3.
• Aggregate bandwidth Nx88 Mbit/s where N = installed dual-TDM cards.

Noise Tolerance:

• Robust frame locking algorithms maintain connectivity on noisy links such as multi-hop, high-BER microwave paths.

Management:

• Inband or out-of-band from either LAN/SFP port.
• SNMP v2c with VACM to limit access to sensitive areas.
• Supported notifications include: link up/down, ds3/e3 line status change, authorization violation, coldstart.
• Full MIB support including ds3, mau, dot3, ifMIB...
• HTTP web status with large BER, LAN/DS3 error codes and packet-auditing statistics.

• 400kByte buffering.

DS3/E3:

• Compatible with C-bit/M13/M23/G.751-framed and unframed links.
• DS3: Generates a C-bit, unchannelized, B3ZS, AMI signal -- 300 meters max.
• E3: Generates a G.751, unchannelized, HDB3, AMI signal -- 480 meters max.

Support/Misc:
