Tellabs 8100 Managed Access System: Tellabs 8110 Network Terminating Unit (CTU-S)
Tellabs® 8100 Managed Access System
Tellabs® 8110 Network Terminating Unit (CTU-S)
High-speed modem designed for managed serial data access.
Overview
The Tellabs® 8110 Network Terminating Unit (CTU-S) is a Network Terminating Unit (NTU) that uses ETSI HDSL-based technology. The high-speed modem has a maximum symmetrical data rate of 4,544 Kbps and it has AC, DC and remote power feed options. The Tellabs 8110 NTU (CTU-S) is connected to the Tellabs® 8100 Managed Access System with the HDSL modules of the OMH-A and the QMH units, which can be used in the Tellabs® 8140 Midi Node, Tellabs® 8150 Basic Node, Tellabs® 8184 Access Switch and Tellabs® 8188 Access Switch.
The Tellabs 8110 NTU (CTU-S) is configured and monitored with the Tellabs® 8000 Intelligent Network Manager. The modem does not require any on-site configuration. However, a handheld VT100 terminal can be connected into the Tellabs 8110 NTU (CTU-S) to obtain the monitoring and status information.
Features and Benefits
Applications
The Tellabs 8110 NTU (CTU-S) high-speed modem is primarily designed for managed serial data access with fast and easy installation. With a G.704 interface it is also suitable for connecting mobile base stations or PBXs to the rest of the transmission network.
Unit Construction
The Tellabs 8110 NTU (CTU-S) is housed in a compact plastic case suitable for tabletop use. LEDs on the front indicate the powering, line, and DTE status. The X.21, V.35 or G.703 DTE interface is integrated as well as the RS-232 interface suitable for VT100 terminal.
End-to-end Network Management
The Tellabs 8110 NTU (CTU-S) is housed in a compact plastic case With the Tellabs 8000 Intelligent Network Manager tools, remote configurations, semi-automated service provisioning, testing, service level fault reporting and performance reporting are enabled. This gives significant savings in operational expenses and shortens the response times throughout the network and service lifecycle.
