Chapter 1. Introduction
1-2 OSU 300 User Manual 61200663L1-1
Complete configuration, diagnostics, and performance monitoring
are available through SNMP, Telnet, or a VT-100 terminal interface.
This connection can be made via Ethernet or a local EIA-232 link.
The OSU 300 is designed for either desktop use or for installation in
a 19-inch rack.
The major features of the OSU 300 are as follows:
• Full feature multiport optical DS3 DSU/CSU
• Maximum of four user data ports: one integrated HSSI port
and three additional slots for optional HSSI, high-speed V.35,
or Quad DSX-1 cards
• Automatic or manual remote configuration
• Embedded SNMP and Telnet management through 10BaseT
Ethernet or SLIP/PPP
• Detailed performance monitoring for local and remote units
• Simplified configuration through detailed VT-100 terminal
menu structure
OPTICAL INTERFACE PORT
• The optical interface of the OSU 300 consists of either a single-
mode or a multi-mode transceiver module comprised of a
transmitter, a receiver, and an SC or ST receptacle.
• The optical interface port supports angled SC type optical
connectors (1200663L1 and L2 only).
• The optical interface port operates in the 1280 nm to 1335 nm
wavelength range (1310 nm nominal).
• The total output power is 8 mW, as defined by IEC with a
50 mm aperture at 10 cm distance.
• The optical interface uses two fibers, one for each direction of
transmission.
• The transceiver optical budgets for the optical transceivers are
28dB (single-mode) and 9 dB (multi-mode). See the Optical
Interface Port section on page 2-7 for calculations.
• The optical interface complies with the physical interface
parameters listed in ITU-T recommendation G 957.
