TDM Pseudowires Overview
A TDM pseudowire acts as Layer 2 circuit or service for T1 and E1 circuit signals across an
MPLS packet-switched network. On ACX Series routers, you configure a TDM pseudowire
with Structure-Agnostic Time Division Multiplexing (TDM) over Packet (SAToP) on the
ACX Series built-in channelized T1 and E1 interfaces. When you configure a TDM
pseudowire, the network between the customer edge (CE) routers appears transparent
to the CE routers, making it seem that the CE routers are directly connected. With the
SAToP configuration on the provider edge (PE) router’s T1 and E1 interfaces, the
interworking function (IWF) forms a payload (frame) that contains the CE router’s T1
and E1 Layer 1 data and control word. This data is transported to the remote PE over the
pseudowire. The remote PE removes all the Layer 2 and MPLS headers added in the
network cloud and forwards the control word and the Layer 1 data to the remote IWF,
which in turn forwards the data to the remote CE router.

Overview of a TDM Pseudowire Base Configuration
The configuration shown here is the base configuration of an TDM pseudowire with T1
framing on an ACX Series router. This configuration is for one provider edge router. To
complete the TDM pseudowire configuration, you need to repeat this configuration on
an other provider edge router in the Multiprotocol Label Switched (MPLS) network.
