Connecting ATM Network Modules
This chapter describes how to connect Asynchronous Transfer Mode (ATM) network modules for Cisco
modular routers and contains the following sections:
•
ATM-25 Network Module, page 11-1
•
ATM T3 and E3 Network Modules, page 11-3
•
ATM OC-3 Network Modules, page 11-5
Tip
To determine whether your router supports a specific network module, see
Table 1-6 on page 1-16
.
ATM-25 Network Module
The ATM-25 network module (see
Figure 11-1
) provides ATM traffic shaping for use with asymmetric
digital subscriber line (ADSL) uplink speeds, and protocol support for permanent virtual circuit (PVC)
environments. The network module provides full support for multiprotocol encapsulation over ATM
Adaptive Layer 5 (RFC 1483), classic IP over ATM encapsulation (RFC 1577), and Point-to-Point
Protocol (PPP) over ATM.
