O3-4D1L3 U2
1631, Issue 4, October 2009
C. Features
The O3-4D1L3 provides the following features:
•
Supports Universal and, by virtue of VT1.5 OC3 mapping, Integrated network
topologies
•
Occupies just two card slots in Type 3192 mechanics shelves— ideal for use in existing
remote terminals (RTs) or central offices (COs)
•
DS1 numbers 1, 2, 3, and 4 mapped into STS-1 VT1.5 #1 positions 1, 2, 3, and 4,
respectively
•
Available Type 400 mechanics version (O3-4D1) suitable for placement at subscriber
sites
•
Climate hardened
•
DS1 lightning protection and – 48 VDC power input surge protection to help assure
reliable service delivery for units installed at cell sites or in other harsh environments
•
Plug-and-play default DS1 provisioning [short loops, bipolar with 8-zero substitution
(B8ZS) and extended superframe (ESF)] and simple front-panel switches that enable or
disable each of the four DS1 ports to eliminate the need to use the craft port for most
applications
•
DS1 line build-out provisioning for 0 to 655 feet as well as 0 dB, 7.5 dB, and 15 dB
•
Support for ESF data link and craft port loopback commands
•
DS1 superframe (SF), ESF, and unframed operation support
•
Instant Default feature that permits restoring all settings to their default state without
the need to use the craft port
•
Utilizes Pulsecom patent-pending “Optionless SONET” technology to eliminate OC3
provisioning
•
Designed to accept OC3 small form-factor pluggable (SFP) 1310 nm, 1550 nm, and
coarse wave division multiplexing (CWDM) transceivers
•
Standard female 24-pin AMP
TM
CHAMP
TM
front-panel DS1 connector
•
Standard DB-9 RS-232 craft port front-panel jack (9600 baud, 8-bit bytes, no parity, and
one stop bit) to access performance information and advanced provisioning capabilities
•
Simple front-panel indicators for OC3, UNIT, and DS1 operating status
•
Alarms that activate alarm indication signal (AIS) and DC contact closures to provide
end-to-end sectionalization
•
Fiber attenuators not required to perform an optical loopback with a fiber jumper when
using the SFP-OC3-1310-19 transceiver
•
Side-by-side mounting compatible with Pulsecom O3D3-1310L3 and O3D3-1550ERL3
units to support DS1 and DS3 services
•
Craft port display of optical transceiver wavelength and link loss budget
