The DS33X162 family of products provide the required flexibility and complexity to meet the needs of a very broad
range of applications. Although typical applications using these devices are very complex and each application has
a unique set of needs, most application developments follow a predictable set of steps:
5.1
The designer of an application using one of the devices in the DS33X162 product line should begin by answering
several high-level questions.
The solutions to these questions, in conjunction with referencing Table 1-1, will lead to a proper device selection:
5.2
The answer to “How many and what type of TDM links are needed?” will normally narrow the selection to devices
that contain at least that many ports. For example, if 16 E1 links are required, the applicable solutions are the
DS33X161 and DS33X162. If 4 DS-3 links are required, the applicable solutions are the DS33X41, DS33X42,
DS33X81, DS33X82, DS33X161, and DS33X162.
The answer to “How does data need to move between the various interfaces of the mapping device?” will usually
further narrow the selection. The path any given frame takes through the device can be determined by the contents
of the frame, the port of entry, the user configured WAN Connections, and the user configured Forwarding Mode.
Note that all devices in the product family allow insertion and extraction of frames for inspection, (including ITU-T
Y.1731 OAM frames) by the host microprocessor, based on a number of conditions outlined in Section 8.17
If traffic flow is to be governed by VLAN tag information, the choices are narrowed to only those devices that
support VLAN forwarding: DS33X42, DS33X82, and DS33X162. If ingress traffic is to be segregated by VLAN ID or
DSCP Priority into separate WAN flows, the available number of WAN Groups in Table 1-1 should be considered.
Several Forwarding Modes govern the flow of frames through the device. See Table 8-4 in Section 8.9 for more
information.
