Description
The Black Box 1500A T1/FT1 CSU/DSUs provide high-speed T1 format processing at speeds from 56 kbps to 1.544 Mbps for V.35 or RS-530 segments in your network. The (Black Box 1500A not only gives you the framing and formatting of V.35 data for transmission across predefined T1 facilities, they also work with both full and fractional T1 services. All models feature a V.35 (M/34) data port for delivering T1/FT1 services to the data terminal equipment (DTE) of your end users.
Whether you need to connect router traffic, plug it directly into a mux’s V.35 interface, bridge networks, or provide video over T1/FT1 lines, the Black Box 1500A T1/FT1 CSU/DSUs deliver. You can also use the Black Box 1500A to terminate a public Frame Relay link for voice, fax, and data. Even though the Black Box 1500A CSU/DSUs support a maximum full-duplex data rate of 1.544 Mbps across the T1/FT1 line, you can set specific speed in 56K (or 64-kbps) increments below that.
The Black Box 1500A T1/FT1 CSU/DSUs go the distance, too! Use them in pairs as line drivers for your point-to-point applications to reliably and economically link two V.35 (or RS-530) devices up to 6000 feet (1828.8 m) apart. The Black Box 1500A CSU/DSUs support AMI/B8ZS line coding and D4/ESF framing on the T1/FT1 line, as well as network interface or internal oscillator clocking. You can control functions with the Black Box 1500A front-panel dome switches.
Plus, you can manage the Black Box 1500A via its standard RS-232 port for local or remote maintenance, monitoring the unit’s ports and network connection. Critical alarm info displays with date and time stamps. What’s more, the Black Box 1500A has a simple menu structure enables you to easily set up and perform diagnostic testing from any VT100™ compatible device through the unit’s serial console port connection.
For troubleshooting, you can also run local and remote loopbacks on both the serial and V.35 network segments and generate test patterns. Four models of the T1/FT1 CSU/DSU are available. In addition to our basic V.35 model (Black Box MT1500A), we offer three SNMP-manageable models
SNMP MIB II co(MT1510A-35, MT1511A, and MT1510A-530), which come with an SNMP agent for setting up real-time alarms and advanced management functions.mpliance means they’re compatible with popular network management systems like HP® OpenView® or SNMPc™. The managed model with DSX (MT1511A) also has a DSX “drop-and-insert” port that enables you to configure your T1 line to share bandwidth capacity for multiplexing a mixture of both voice and data traffic.
