Nortel Networks 7400 - Manual (Page 28)

Technical Specifications
• Carrier-class NEBS level 3 compliance - meeting the
most rigorous electrical, environmental,
temperature and vibration standards for
reliability.
• Dual Gigabit Ethernet ports using provisionable
Multi-Link Trunking (MLT) - load sharing between
the two Gigabit Ethernet ports enables bandwidth
to be increased and ensures availability of service
with sub-second failover.
• Varying access or UNI options to meet service
demands and transport alternatives (10/100 Mbps,
100 Mbps, GE, copper, fiber). See Table 1 for UNIs
on each of the OPTera Metro 1000 modules.
• Two Gigabit Ethernet uplink options: one or two
1000BASE-TX uplink ports or a dual-port Small
Form Factor Pluggable (SFP) Gigabit Interface
Connector (GBIC) - ensuring cost-effective
transport over fiber, RPR and/or DWDM.
• Services for up to 500 customers per OPTera Metro
1000 device, by using a Transparent Domain
Identifier (TDI)/VPN Identifier (VPN-ID) for each
customer.
• Quality of Service (QoS) and Service Level
Agreement (SLA) support through: tunable
bandwidth from 1 Mbps to 100 Mbps in
increments of 1 Mbps per port or per TDI/VPN-ID,
802.1p and DSCP priorities mapping, utilisation of
4 UNI egress queues and 8 NNI egress queues.
