Client Interface

For 2R operation mode, the TXP_MR_2.5G and TXPP_MR_2.5G cards have the ability to pass data

through transparently from client side interfaces to a trunk side interface, which resides on an ITU grid.

The data might vary at any bit rate from 200-Mbps up to 2.38-Gbps, including Enterprise System

Connection (ESCON) and video signals. In this pass-through mode, no performance monitoring (PM)

or digital wrapping of the incoming signal is provided, except for the usual PM outputs from the Small

Form-factor Pluggable (SFPs). Similarly, this card has the ability to pass data through transparently from

the trunk side interfaces to the client side interfaces with bit rates varying from 200-Mbps up to

2.38-Gbps. Again, no performance monitoring or digital wrapping of received signals is available in this

pass-through mode.

For 3R operation mode, the TXP_MR_2.5G and TXPP_MR_2.5G cards apply a digital wrapper to the

incoming client interface signals (OC-N, 1G-FC, 2G-FC, GE). Performance monitoring is available on

all of these signals except for 2G-FC, and varies depending upon the type of signal. For client inputs

other than OC-48/STM-16, a digital wrapper might be applied but the resulting signal is not

ITU-T G.709 compliant. The card applies a digital wrapper that is scaled to the frequency of the input

The TXP_MR_2.5G and TXPP_MR_2.5G card has the ability to take digitally wrapped signals in from

the trunk interface, remove the digital wrapper, and send the unwrapped data through to the client

interface. Performance monitoring of the ITU-T G.709 OH and SONET/SDH OH is implemented.
