DSL and G.SHDSL Connectivity

DSL technologies remain valuable in environments where existing copper infrastructure needs to be reused for broadband or data transmission. Raisecom has developed G.SHDSL modem solutions for transporting Ethernet, V.35, E1, and other services over copper infrastructure.

These solutions provide a practical alternative where deploying new fiber is difficult or uneconomical, while allowing organizations to maintain reliable connectivity across existing cable infrastructure.

Typical DSL Applications

Raisecom DSL modem equipment can support:

• Enterprise WAN connectivity
• Leased-line applications
• Ethernet extension over copper
• E1 transmission
• V.35 data connectivity
• Remote site communications
• Industrial networking
• Telecommunications access networks

Fibre Optic Multiplexers

Raisecom fiber optic multiplexers are designed to aggregate multiple communication channels and transport them efficiently over optical infrastructure. These systems can combine voice, data, Ethernet, TDM, and other services within a common fiber transport architecture.

Raisecom's Multi-Service Access Platform specifically includes multi-service fiber multiplexers alongside mini-SDH, interface converters, and modem solutions.

Historical Raisecom PDH optical multiplexers also supported E1 and V.35 services over single- or dual-fiber connections, with certain platforms providing multiple E1 channels over distances of up to 120 km.

Efficient Optical Data Transport

Fiber multiplexing enables network operators to:

• Aggregate multiple services onto fiber
• Increase utilization of existing optical infrastructure
• Extend communication over long distances
• Connect remote network locations
• Transport TDM and Ethernet services
• Reduce the need for separate physical links
• Build flexible point-to-point access networks

SDH Multiplexing Equipment

Synchronous Digital Hierarchy (SDH) remains an important technology in many carrier, utility, transportation, and mission-critical communication networks. Raisecom provides SDH-based equipment designed to aggregate, transport, and manage multiple telecommunications services across optical infrastructure.

Raisecom's portfolio includes mini-SDH and multi-service platforms as well as larger optical transport systems. The iTN8600-A, for example, incorporates SDH, OTN, and packet transport switching capabilities and can operate as a next-generation SDH multiplexer when configured with appropriate line cards.

Supported services can include Ethernet, E1, STM-1, STM-4, STM-16, and Fiber Channel, depending on platform and configuration.

SDH Network Capabilities

• STM-based optical transmission
• SDH service aggregation
• E1 and Ethernet transport
• Multi-service access
• Optical network aggregation
• Redundant network architectures
• Flexible clocking
• Legacy TDM network support
• Migration toward packet transport

PDH Multiplexing Equipment

Plesiochronous Digital Hierarchy (PDH) equipment provides a reliable method for transporting multiple digital communication channels over optical or electrical transmission infrastructure.

Raisecom's PDH multiplexing solutions have been used for E1, V.35, Ethernet, voice, and other telecommunications services. Certain optical PDH multiplexers support multiple E1 channels over fiber and can operate in point-to-point architectures.

These products are particularly relevant to legacy telecommunications networks, utility communications, transportation infrastructure, and other environments where established E1 and TDM services remain operational.

Multi-Service Access

A key feature of Raisecom's telecommunications portfolio is the ability to transport multiple service types across a common access infrastructure.

Raisecom's multi-service platforms support combinations of Ethernet, E1, STM, serial data, voice, and other interfaces. Its mission-critical solutions can provide interfaces such as STM-1, E1, Ethernet, FXS/FXO, E&M, RS-232, RS-422, RS-485, G.703, and C37.94, depending on platform configuration.

This allows service providers and infrastructure operators to consolidate different communication requirements within a unified access platform.

SDH and Packet Network Migration

Raisecom's modern multi-service architecture is designed to help organizations transition from traditional SDH and TDM infrastructure toward packet-based networking.

Its dual-backplane architecture can combine SDH and packet transport technologies, supporting migration toward Carrier Ethernet, MPLS-TP, and IP/MPLS networks.

This approach is particularly valuable for organizations operating long-lived telecommunications infrastructure that cannot be replaced immediately.

Legacy-to-IP Migration

Raisecom solutions can help organizations:

• Preserve existing TDM services
• Introduce Ethernet-based transport
• Integrate SDH with packet networks
• Support E1 pseudowire applications
• Maintain legacy interfaces during migration
• Improve network scalability
• Gradually modernize access infrastructure

Optical Transport and DWDM Integration

Beyond traditional SDH and PDH equipment, Raisecom's optical transport portfolio extends into OTN and DWDM technologies.

Its iTN8600 platform can be configured as an OTN/DWDM transport system, Carrier Ethernet or MPLS-TP aggregation platform, or next-generation SDH multiplexer. Its optical cards include DWDM MUX/DEMUX modules, CWDM modules, optical add-drop functions, optical line protection, and optical amplification.

This creates a migration path from conventional TDM transport toward higher-capacity wavelength-based optical networks.

Network Reliability and Redundancy

Carrier and mission-critical networks require high availability and protection against equipment or link failures. Raisecom provides redundancy features across selected access and transport platforms, including redundant power supplies, switching matrices, cross-connect architectures, and optical protection.

Its mission-critical multi-service platform is designed with redundant system components and flexible clocking options to support reliable communications.

Optical transport platforms can also incorporate optical line protection and redundant network architectures for improved service continuity.

Network Management

Raisecom access platforms support centralized management and operational monitoring, allowing network administrators to configure equipment, perform diagnostics, monitor network conditions, and manage remote devices.

The RC001 chassis family, for example, provides SNMP-based management functions including configuration management, diagnostics, loop activation, monitoring, and fault management for installed modules.

These capabilities simplify the operation of distributed telecommunications infrastructure and reduce the complexity of managing equipment across multiple locations.

Carrier and Enterprise Applications

Raisecom equipment can support a broad range of applications, including:

• Telecommunications carrier networks
• ISP and broadband access
• Enterprise WAN connectivity
• Leased-line services
• Fiber optic access networks
