4.2 Circuit Emulation Services
The MT9088x family can be used to transport TDM links across the packet domain and transparently reconstruct
the links at the far end (Figure 3). This is similar to the circuit emulation services defined by the ATM Forum, with
the MT9088x device providing the circuit emulation inter-working function.
The part is capable of handling circuit emulation of both structured and unstructured DS1 (T1) and E1 links. The
use of an Ethernet packet infrastructure for this facilitates the extension of TDM services between locations using
easy to manage and readily available network hardware.
The part supports dynamic bandwidth management, by providing the ability to add and delete timeslots from the
packet stream as required. A cross-connect service can also be provided by using an Ethernet switch to route
packet streams to different destinations.
