Phoenix Microsystems 5575 T1 Micro-BERT Test Set
The Phoenix Model 5575 T1 Micro Bert is a full function
T-carrier line tester designed for use on 1.544 Mbps T-carrier links. The removable top cover serves as the storage area for the
interface cables. A two line by forty column LCD display, 14 status/alarm
LED indicators, and a 24-key keyboard with internal status LEDs on each
key, provide the operator with a full function, easy to use tester, in a
small, portable package.
Design Highlights:
- One button full testing with automatic line
evaluation and setup
- Portable, handheld, battery powered
- Tests D4 framed, extended superframe, SLC(r)96
framing, or unframed links
- Direct connection to TelCo "T" interface
- CSU emulation mode
- Generates and receives 12 test patterns plus user
defined pattern
- Network ALBO and LBO
- Complete self-test functions
- Operates from internal battery, line power using
adapter, or local central office battery
- Real time clock (time, day, date)
- Full remote control RS-232 port
- Twenty column printer port via a second RS-232 port
Input Specifications:
Input Connectors: WECO 310
jack and 15-pin, D-shell network interface connector.
Input Frequency: 1544000 Hz +/- 300 Hz
Line Codes: AMI or B8ZS (B8ZS is available in framed modes only.)
Input Impedance:
Bridge: Greater than 1000 ohms
Term: 100 ohms +/- 5%
Monitor: 100 ohms +/- 5%
CSU: 100 ohms +/- 5%
Operating Range:
Bridge: +6 dbdsx to -20 dbdsx, Automatic Line
Build Out (ALBO), compensates for cable loss
Term and CSU: +6 dbdsx to -20 dbdsx, Automatic
Line Build Out (ALBO), compensates for cable loss
Monitor: +6 dbdsx to -6 dbdsx, ALBO provided with
fixed +20 db amplifier to compensate to DSX monitor series impedance
losses.
Transmit Mode: The transmitter is disabled and completely isolated
from the output jacks in the Bridge and Monitor mode. This allows the 5575
to utilize the Tx jack as a secondary receiver to measure voltage,
frequency, and loop timing of both sides of the span for in-service
specifications.
Output Specifications:
Line Build Out (LBO): Switch selectable with 0, -7.5, and -15 db attenuation.
Output Connectors: Provided on WECO 310 jacks and 15-pin D-shell
network interface connector.

Line Codes: AMI or B8ZS
Pulse Shape: Complies with AT&T Pub. 62411 and CCITT
Recommendation G.703 when terminated in 100 ohms and 0 db line build out
selected.
Jitter: Complies with AT&T Pub. 62411
Front Panel Indicators Specifications:
Alarm Indicators: Frame
Sync Loss, All Ones (Blue Alarm), Density (excess zeros and insufficient
ones), and Yellow Alarm.
Status Indicators: Frequency Deviation, Line Level Fault, Not Loop
Timed, Low Battery, Signal Present
Sync Indicators: Pattern sync, D4 frame sync, ESF sync, and
SLC(r)96
Coding Indicators: AMI and B8ZS
Alarm Criteria Specifications:
Pattern Sync Loss: Programmable from 0-9999 bit errors in 0-9999 bits. Factory setting is 100
bit errors in 1000 or fewer bits.
Frame Sync Loss:
D4: 2 out of 5 Ft. bits in error
ESF: 2 out of 5 Ft. bits in error
SLC(r)96: 2 out of 5 Ft. bits in error
