•
Full channelization of DS3 to DS0 (CEM mode only).
•
Bellcore GR-253-CORE SONET/SDH compliance (ITU-T G.707, G.783, G.957, G.958).
•
The SPA-1CHOC3-CE-ATM uses small form-factor pluggable (SFP) optical transceivers, allowing the
same SPA-1CHOC3-CE-ATM hardware to support multimode (MM), short-reach (SR) fiber,
intermediate-reach (IR1) fiber, and long-reach (LR1 and LR2) fiber, depending on the capabilities of
the SPA.
•
OIR of the individual SPA-1CHOC3-CE-ATM from the SIP that is installed.
•
CEM local switching and local switching redundancy.
The basic features supported by the 2-Port Channelized T3/E3 ATM CEoP SPA are:
•
It can be deployed for ATM services that deliver high-performance interconnectivity, metro, and intra-POP
applications between a service provider
’
s points-of-presence (POP) for IP or Multiprotocol Label
Switching (MPLS) transport.
•
It can be deployed in the customer-premises equipment (CPE) to provide data components to the service
provider networks.
•
In Cisco IOS XE Release 3.4.0S, the 2-Port Channelized T3/E3 ATM CEoP SPA supports only the
clear-channel T3 ATM mode.
•
Effective from Cisco IOS XE Release 3.5.0S, the 2-Port Channelized T3/E3 ATM CEoP SPA supports
the clear-channel E3 ATM mode and the clear-channel T3 ATM mode.
•
Provision to set the clocking mode to either local timing or loop timing (default) for individual DS3/E3
paths.
•
The DS3 and E3 alarms reported are:
◦

•
It supports the ATM MPLS encapsulation and Internet Engineering Task Force (IETF) RFC and drafts.
•
It is compliant with the IETF standards for CESoPSN and SAToP.
•
It provisions full channelization of DS3 to DS0 (CEM mode only).
