Lucent Technologies Inc.
Small and Large TSIs
The TTSI1K16T is one in a family of time-slot interchanger (TSI) devices offered by Lucent Technologies Micro-
electronics Group. This family of devices are all software compatible since they all have similar register maps. The
larger devices of course have extra registers to configure the extra highways and also have larger connection and
data stores. However, software written for a smaller TSI will run without alterations with a larger device. The
TTSI2K32T and TTSI4K32T are also pin compatible, since they are in the same package.
The capacity of the TTSI1K16T can be fully utilized by receiving and/or transmitting data on all 16 highways at
4.096 Mbits/s or eight highways at 8.192 Mbits/s. Similarly, the TTSI2K32T can be fully utilized by receiving and/or
transmitting data on all 32 highways at 4.096 Mbits/s or 16 highways at 8.192 Mbits/s. Other combinations of differ-
ent data rates on different highways can also be used to fully utilize the TTSI1K16T and TTSI2K32T. The capacity
of the TTSI4K32T is fully utilized only when data is being received and/or transmitted on all 32 highways at
8.192 Mbits/s.
The TTSI4K32T can be used to make even larger switches; for example, an 8192 time-slot switch with 64 Rx and
64 Tx highways. The Rx and Tx highways of the 8K switch are labeled LRXD[0—63] and LTXD[0—63], respec-
tively, in the figure below.
5-7076(F)r.1
Figure 4. An 8K Time-Slot Switch Made from 4K TSIs
LRXD[0—31] are sent to both TSI #1 and #2. Similarly, LRXD[32—63] are sent to both TSI #3 and #4. The
TXD[0—31] of TSI #1 are wire-ORed with the TXD[0—31] of TSI #3, to make LTXD[0—31]. Similarly, the
TXD[0—31] of TSI #2 are wire-ORed with the TXD[0—31] of TSI #4, to make LTXD[32—63].
Now, if time slots on highway LRXD0 need to be switched to LTXD63, it can be done via TSI #2. The connection
stores of TSI #2 and #4 must be programmed such that they both never drive their TXD31 simultaneously. The
3-state per time-slot feature of the TSI allows this to be accomplished easily.
