ATM-25 Network Module

The ATM-25 network module (see Figure 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.

Connecting Cisco ATM Network Modules to the Network ATM OC-3 Network Modules Power Budget and Power Margin Proper operation of an optical data link depends on modulated light reaching the receiver with enough power to be demodulated. The power budget (PB) is the difference between transmitter power (PT) and receiver sensitivity (PR).

Dispersion is usually negligible for single-mode fiber. For multimode fiber, the product of bandwidth and distance should be less than 500 MHz-km.
