ULAF V4.0 consists of the following units:
BSTU Key features (1)

BSTU is new termination unit based on latest SHDSL technology. The
unit replaces STU and STU2, which will be phased-out.
Enhanced SHDSL performance using the 3rd generation of SHDSL

transceivers
Support of SHDSL.bis transmission with line codes TC-PAM16 (line
speed up to 3848kbit/s per UTP) and TC-PAM32 (line speed up to

5696kbit/s per UTP) according to ETSI TS 101 524 and ITU-T G.991.2
recommendations
New operation mode add/top with full E1 + data via one or two UTPs
Automatic adjusting of SHDSL line rate possible (Lock bitrate
on/off)
page 3
SHDSL features
Embedded clock mode and enhanced jitter/wander

suppression
enable the applications for clock distribution (e.g. in mobile
networks)
Advantages of the new design
High integration and flexibility

Extended mapping features compared with STU and STU2:
flexible time slot allocation for voice, data and signaling.

Ethernet switch (10/100BaseTx) fully configurable with
1 or 2 SHDSL ports
1 or 2 x E1 interfaces
Ethernet switch (10/100BaseTx) on board
Data module slot
Versions with Remote Power Supply (RPS) generate 120/180VDC and
50/60mA for the remote feeding of BSRUs and/or BSTU desktop units
Applications using 2 UTPs:

One system: E1 or data distributed into 2 UTPs with half line bit
rates to achieve longer distances or
Two independent systems: each E1 interface allocated to one
UTP; add/drop mode fractional E1 + data or Ethernet also possible

using Ethernet switch on board or data interface module
