NMC-RX 7.3.x User Guide, Vol. 1 > Configuring Unchannelized OC Modules > Overview

Overview

The NMC-RX application supports OC modules that provide high-speed communications between E-series routers and core routers in an ATM network. Several versions of unchannelized OC modules can be configured with the NMC-RX application.

OC line modules pair with I/O modules to provide particular capabilities and connections. For more information about unchannelized OC modules, see Table 43 and the JUNOSe Physical Layer Configuration Guide.
