Overview of the Circuit Emulation over Packet Shared Port Adapter
• 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 AAL0—Cell mode.
• It supports the ATM AAL5—Packet mode.
• It supports the AToM feature, such as Cell Relay.
• It supports the ATM MIBs.
• It supports the Any Transport over MPLS over Generic Routing Encapsulation (ATMoGRE).
• It supports the Any Transport over MPLS Operation, Administration, and Maintenance (AToM OAM)
(segment mode or emulation mode).
• It supports the Any Transport over MPLS Pseudowire (AToM PW) redundancy.
• 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).
