SpectraComm IP Ethernet Extension

A powerful technology is now available from General DataComm to help Carriers reduce costs while expanding their internal IP networks, increasing revenues and providing a high margin IP service offering. SCIP LAN-X extends the reach of IP connectivity with value-added features and benefits:

• Increases revenues and service offerings
• Reduces hardware and network maintenance costs
• Simplifies installations and network management
• Low-cost and highly reliable transparent Ethernet LAN over standard T1/FT1, E1/FE1, DDS or xDSL circuits.
• Supports scalable high performance LAN via standard 10/100BASE-T Ethernet
• Provides full redundancy and loop elimination with standards-based Spanning Tree Protocol (STP)
• Telco-tough NEBS Level III-compliant packaging for Central Office sites
• Reduced power consumption
• Flexible packaging for remote sites

As Carriers and PTTs expand and provision the use of equipment in their networks, the 100-meter distance limitation of standard Ethernet can become an issue. By extending the LAN over longer distances, the network architecture can be simplified and the need for expensive routers is eliminated. GDC's SCIP LAN-X offers out-of-band management solutions for LAN-attached IP devices over standard FT1/T1, E1/FE1, DDS or xDSL circuits. LAN extension between floors or between buildings uses the available digital technology for timely installation and management of services over existing facilities. This same technology can be used to offer transparent LAN services (TLS) to customers as a new TLS service offering.

• Low-cost, reliable routing or LAN-extension
• Supports scalable high performance LAN via 10/100BASE-T Ethernet
• Telco-tough NEBS Level III Certified

As Carriers introduce IP equipment to their networks, GDC offers two access solutions for LAN-attached IP devices and legacy (Craft Port) devices. Either mode of operation can be conducted over the Carrier's T1/FT1, E1/FE1 or DDS network, as well as over a dial-up PSTN.

• In LAN-X mode, the SC-IP can be deployed as a LAN or "Transparent Ethernet" extension device for those remote locations where a single 'flat' IP network is required.

• In router mode, the SpectraComm IP (SC-IP) provides management access by extending the Carrier's internal network to remote locations where separate IP networks are required.

When additional NEBS-compliant Ethernet connectivity is required, SC-IP can integrate with SpectraComm Ethernet Switch (SC-ES) cards, offering scalable IP connectivity in 9 or 18 port increments.

SpectraComm IP G.shdsl.bis

SpectraComm IP G.shdsl.bis allows Ethernet connectivity beyond the 100-meter distance limitation without the need for expensive routers. LAN extension can be accomplished with GDC's SCIP G.shdsl.bis which transports data on copper loops at rates up to 5.632 Mbps on a single loop or 11.264 Mbps on 2-loops for LAN-attached IP devices.

LAN extension between floors or between buildings using DSL technology allows timely installation and management of services over existing facilities. SCIP G.shdsl.bis delivers a reliable Ethernet extension solution for use in first mile, symmetrical, Ethernet deployments.

In the event of a loop failure, SCIP-G,shdsl.bis in 4-wire mode performs auto-fallback to single loop operation, and two-loop restoral when the failed loop recovers. Auto-fallback and Auto-restoral functions are individually enabled/disabled.

Each SCIP G.shdsl.bis unit comes equipped with two 10/100 Base-T ports and eight terminal server ports for connection to customer equipment, and is fully managed. For applications that require scalable Ethernet connections, the SpectraComm Ethernet Switch, (SCES) companion product can be deployed in 9- or 18-port increments.

SpectraComm ES

• NEBS-compliant ethernet switching for applications where high-quality, high-reliability, security and lowcost are needed.

• Scalable 10/100Mbps connectivity in 9- or 18-port increments, using the existing infrastructure.

• Ideal for remote LAN access applications when used with its companion product, the SpectraComm IP static router, or any other bridge/router device.

• Flexible and secure management options.

The SpectraComm Ethernet Switch provides fast ethernet connectivity for internal networks, allowing a Carrier to efficiently and securely manage LAN-attached equipment. As part of the GDC SpectraComm family of products, SpectraComm Ethernet Switches offer the high reliability and NEBS safety required in Carrier environments. SC-ES can be deployed as a replacement to legacy hubs or in new installations where fast ethernet switching is desired.

The SpectraComm ADT (Asynch Data Transfer) allows Carriers and Enterprise Users to support and manage remote equipment that traditionally would require direct craft port connecton. This is accomplished by encapsulationg the asynchronous traffic and transporting the information via a secure and safe Ethernet as if it were a LAN-based application. Users can now access any craft port device on the LAN via telnet. In cases were direct LAN access is not available, connectivity can be provided via a dial-up connection using SpectraComm ADTs'integral modems. A convenient telnet menu allows device delection by description field or port number.

SpectraComm ADT also provides support for telemetry and security applications. Each SpectraComm ADT device provides up to eight contact input ports for sensing activation of an open or closed contact; and up to two contact output ports to open and close a local contact relay. SpectraComm ADT detects a contact change from its normal state and, depending on its congfiguration, will send an alarm trap, transport the contact state, or perform both trap and transport actions. A "clear" trap is sent when the contact returns to the normal state.

SpectraComm SDT

The SpectraComm SDT (SC-SDT) allows the transport of synchronous data traffic via standards based Ethernet. This is accomplished by encapsulating the synchronous traffic and transporting the information as if it were a LAN-based application.

SpectraComm SDT supports three individually configurable ports and a single Ethernet uplink. Each synchronous data port is configurable for rates from 2400bps to 2.048 Mbps. For applications over distances beyond the limitations of Ethernet, the SpectraComm SDT can be attached to any existing router for transport via the Wide Area Network (WAN) to the desired location. For new installations, GDCs SpectraComm IP family of routers can provide WAN connectivity using T1/FT1, E1/FE1 or G.SHDSL

SpectraComm SDT also provides support for telemetry and security applications. Each SpectraComm SDT device provides up to eight contact input ports for sensing activation of an open or closed contact; and up to two contact output ports to open or close a local contact relay. SpectraComm SDT detects a contact change from its normal state and, depending on its configuration, will send an alarm trap, transport the contact state, or perform both trap and transport actions. A clear trap is sent when the contact returns to the normal state.

DataComm Blade Adapter

The DataComm Blade Adapter allows you to use GDCs newest products without having to invest in additional shelves and provides new networking options. Beyond the legacy DataComm products that were supported by the DataComm series shelves, you will now be able to utilize existing DataComm shelves for SpectraComm and InnovX products that are direct replacements with all the features of the older DataComm series. In addition, you will be able to install GDCs new line of IP Routers, Ethernet switches and asynchronous and synchronous serial data-to-Ethernet adapters. Every new single blade product can be supported in the same shelf. As DataComm slots are used up, transition to the newer SpectraComm and InnovX platforms is simple with no compatibility or sparing issues.

Because the DataComm Adapter is compatible with all single blade line-by-line devices from both GDCs flagship SpectraComm Carrier family and the InnovX Enterprise family of products, existing DataComm shelves can now support an expanded range of applications that include; DDS, FT1, T1, T3, DSL, IP/Ethernet along with modems.

What's Your Network Cost?

How Secure Is Your Network?

Modem Security Radius, Steadfast AES Encryption

Network security is a high priority for any enterprise and information network that stores or provides access to critical assets. General DataComms SpectraComm family of systems and network devices support SteadFast Modem Security solutions that protect your network assets from attacks by illegal users and malicious hackers. GDC systems and products are designed with rigorous security solutions that meet the requirements of mission-critical network applications, such as service provisioning, banking and financial communication, transportation and governmental agencies. GDCs proven telco-tough SpectraComm SteadFast solutions give network administrators a suite of protection options for their large or small network environments,including Security, Authentication, Encryption and Disaster Recovery. SteadFast Modem Security solutions protect network assets by blocking disruption of service due to data theft, data corruption, illegal intrusions, shutdowns, line failure and component failure.

RADIUS Security for Legacy Applications

To answer many of the Internet's security needs, a new standard of authentication was required. Remote Authentication Dial In User Service (RADIUS) brought a client-server architecture to ISPs, enabling efficient, secure authentication of dial-in users. RADIUS manages a database of users, provides authentication so that the dial-in user is allowed access, and delivers configuration information detailing the type of service to provide to the user -- such as SLIP, PPP, telnet, etc.

Just as RADIUS answered the needs of ISPs for security, network managers can use dial-in serial connections for remote management, providing contact with every device in the network. This provides the perfect way to authenticate users of legacy equipment and applications.

GDC's SpectraComm Manager (SCM), Dual V.34 and single SpectraComm V.34 modems' management support RADIUS Security. The V.34 modems prompt the user for name and password and forward this information to the RADIUS server. The RADIUS server authenticates the user and returns a message to the modem to grant or deny access. Optionally, the RADIUS server may challenge the remote user and request additional information before granting access.

Steadfast Security®

GDC modems offer "hacker" protection through our SteadFast Security®. This exclusive system delivers two levels of first line security:

AES Encryption

AES Encryption employs the Advanced Encryption Standard which is a symmetric 128-bit block data encryption technique. AES Encryption takes plain-text data and encrypts it according to the AES algorithm to generate cipher-text data. AES is an approved FIPS-197 U.S. Government encryption standard.SpectraComm VF 28.8, Dual V.34, V.34 and V.34 4-Port modems support the AES (Rijndael) encryption standard. The user configures the modem for AES Encryption by entering an encryption key via AT commands at one of the modems management interfaces Telnet connection through the SCM, the SCM craft port, or the modems DTE interface). AES Encryption allows each modem to take transmit/receive asynchronous data and encrypt/decrypt it on a dial-up or private line network.

Secure Access Controller

The Secure Access Controller (SAC) system employs a factory- optioned GDC V.34 modem to authenticate remote users attempting to access protected network equipment, such as switches, routers, multiplexers, etc. and then AES Encrypts data once the user is authenticated. SpectraComm V.34 and Dual V.34 modems support the Secure Access feature. The modem is user-configured via extended AT commands typed at one of the modems management interfaces (Telnet via the SCM, the SCM craft port, or a terminal connected to the modems DTE connector).
