SATURN QUAD USER NETWORK INTERFACE FOR J2, E3, T3
S/UNI-QJET can be configured as a quad J2/E3/T3 framer for use in router,
frame relay switch and multiplexer applications (as shown in Figure 2). In an
unchannelized J2/E3/T3 line card, S/UNI-QJET interfaces directly to one or more
PM7366 FREEDM-8 HDLC controllers. Each FREEDM-8 can process two high-
speed links, such as T3 and E3, or it can process up to eight lower speed links
such as J2. The S/UNI-QJET can gap all the overhead bits such that only the
payload data is passed to and from FREEDM-8. On the line side, S/UNI-QJET is
connected to one or more J2/E3/T3 line interface units. On the system side,
S/UNI-QJET interfaces with a data link device over a serial bit interface.
In a PPP-Over-SONET application, the S/UNI-QJET interfaces to PM5342
SPECTRA-155 to map three T3 data streams onto three corresponding STS-1
services that are collectively carried over an OC-3 link.
