Features and Benefits
The Cisco 8-Port Channelized T1/E1 SPA Version 2 offers many advantages, including:
●
Eight software-configurable T1 or E1 ports
●
Support for channelized and fractional T1 and E1, as well as clear channel E1
●
256 independent HDLC channels
●
Integrated CSUs and DSUs
●
Support for all major encapsulations, including MLPPP and multilink Frame Relay (MLFR)
●
Support for link fragmentation and interleaving (LFI) over Frame Relay and MLPPP
The Cisco SPA and SIP portfolio offers the following additional advantages:
●
Modular, flexible, intelligent interface processors
◦
Superior flexibility, supporting a combination of interface types on the same interface processor for
consistent services, independent of access technology
◦
Pioneering programmable interface processors that provide flexibility for the service diversity required in
next-generation networks
◦
Innovative design that supports intelligent service delivery without compromising on performance
●
Increased speed-to-service revenue
◦
The scalable, programmable Cisco architecture extended to 10 Gbps significantly improves customer
density, increasing potential revenue per platform.
◦
Interface breadth (copper, channelized, POS, ATM, and Ethernet) on a modular interface processor
allows service providers to roll out new services more quickly, helping ensure that all customers, large
and small, receive consistent, secure, and guaranteed services.
◦
High-density Small Form-Factor Pluggable (SFP) interfaces are featured for high-port-count applications
with reach flexibility. Future optical technology improvements can be adopted using existing SPAs.
●
Improved return on your routing investment
◦
Improved slot economies and increased density help reduce capital expenditures (CapEx).
◦
The ability to easily add new interfaces as they are needed facilitates a "pay-as-you-grow" business
model.
◦
SPAs are shared across multiple platforms and can be moved easily from one to another, providing
consistent feature support, accelerated product delivery, and a significant reduction in operating
expenses (OpEx) through common sparing as service needs change.
