- Page 2 MGX 8220 System Overview MGX 8220 System Overview The MGX 8220 shelf is designed on the philosophy that large scale deployment of narrowband and medium-band services is best handled using an ATM infrastructure. In fact, support of these services can, by themselves, justify an ATM infrastructure. The same infrastructure can then be used to provide broadband services to customers when and where they are needed.
- Page 3 Aggregation of Traffic into ATM Networks Each MGX 8220 shelf connects to the BPX switch across a T3 or E3 ATM STI (Cisco Trunk Interface) to a BNI module on the BPX switch. Thus, the MGX 8220 shelf Release 3.0 supports aggregation of traffic up to 40 T1 or E1 access ports or up to 1240 64-Kbps subscribers, onto a single T3 or E3 trunk, using only a single port on the BPX switch.
- Page 4 MGX 8220 System Overview MGX 8220 Cards MGX 8220 cards are always installed as a pair consisting of a front card (function module) and a matching back card (line module) in the same slot, except for the SRM-T1E1 card which only has a front card.
- Page 5 • Service Resource Module (SRM-T1E1) This card provides loopback and bit error rate testing (BERT) functions and 1:N redundancy for the service modules. The ASC and the BNM modules must be present in an MGX 8220 shelf and are referred to as the core modules.
