Top 5 blogs help accelerate awareness and engagements by a factor of 5!

Expansion Bank Control (EBC-3)

T1000
  • Enables simple system expansion and control for expansion shelves
  • Supports transport of ATM, Ethernet and TDM traffic between shelves
  • Interfaces to an ELU-3 plug-in card in a primary shelf
  • Generates status updates to the CPU via the ELU plug-in card
  • CRC protection on the expansion link
  • Dual memory support for non-service affecting programming
  • Receives DDS timing from the primary shelf
  • Ability to derive timing reference from expansion shelf and transport it to primary shelf via the ELU plug-in card

Expansion Link Unit 3 (ELU-3)

T1000
  • Enables simple system expansion and control for expansion shelves
  • Supports transport of ATM, Ethernet and TDM traffic between shelves
  • Communications gateway between the CPU-3 and the expansion shelves
  • Dual memory support for non-service affecting programming
  • Ability to recover timing reference from the expansion shelf and provide it to the primary shelf
  • Provides composite clock P-Bits and N-Bits to the expansion shelf for DDS timing in the expansion shelf

Gigabit Ethernet Transceiver 222 (GbE222)

T1000
  • Dynamic MAC learning with support for up to 8,000 MAC addresses
  • 4096 VLANs (802.1q) and stacked VLAN support (IEEE 802.1ad)
  • Retain, add, modify and remove subscriber VLAN (C-Tag) and network VLAN (S-Tag)
  • Queuing priority (IEEE 802.1p) and mapping to Asynchronous Transfer Mode (ATM) Quality of Service (QoS) traffic profiles
  • Data services such as Transparent LAN Service (TLS)
  • Traffic management on a per flow basis
  • Multicast support with IGMP Snooping and Proxy for IGMPv2 and IGMPv3
  • Dual memory for minimal service interruption during programming/software upgrades
