TSW200E1
• Polarity: see section 5.3.1
• Tx Clk Src: see section 5.3.1
• Interface: Selects the interface to use. It is possible to choose between V.24/RS232,
V35, V36, X.21 or RS530. To change the option place the cursor at the proper line and
use the ← or → keys to toggle between the interfaces.

5.6 - The DEMUX mode
The DEMUX mode allows the user to perform demultiplexer tests. The TSW200E1
transmits 2 Mbps data in one or more timeslots from the multiplexer side. Frame structure is
supported. From the other side of the multiplexer, data in one or more channels can be monitored
using one of the following interfaces: V.24/RS232, V.35/V.11, V.36/V.11, X.21/V.11 or RS530.
The counter options in the DEMUX mode are BIT ERROR, BLK ERROR, BLOCKS, SLIP
(as in ITU-T Rec. G.822), PAT.LOSS, RX RATE and TIME. For the BIT ERROR counter, the
TSW200E1 performs the following error analyses:
• errored seconds (ERRORED SEC.)
• severely errored seconds (SEV. ERR. SEC.)
• degraded minutes (DEGRADED. MIN.)
• available seconds (AVAILAB. SEC.)
• unavailable seconds (UNAVAIL. SEC.)
• error-free seconds (ERR. FREE SEC.)
• rate between errored bits and the total number of bits transmitted (BER)
• rate between errored blocks and the total number of blocks transmitted (BLER)
