Select the control board by chassis class and performance target. CCU-N-ALDER covers the full UCP family; CCU-I-TGL is for UCP2120 and UCP4131.
Unified
Communication
Platform
UCP is a modular unified communication platform solution that brings control, switching, telephony interfaces, wireless access, audio, radio, and storage modules into one chassis system. It helps integrators build stable, reliable communication platforms that can be configured around each project.
Choose the UCP chassis before choosing interface boards.
A one-control, one-service-slot UCP chassis for small offices, pilot deployments, and dedicated gateway nodes that need modular communications in a compact form factor.

Map chassis slots, control boards, service boards, and storage before choosing a UCP system.
Confirm chassis capacity, control and switching architecture, service access, and storage or RAID requirements before configuring boards.
UCP1202 provides 2 built-in Gigabit Ethernet ports. Rackmount chassis use CSU-F or CSU-G boards for dedicated switching expansion.
Combine service boards for the required access mix: analog endpoints, wireless trunks, E1/T1/J1 links, radio dispatch, magneto lines, and audio control.
Use SEU for local SATA expansion on supported chassis, and specify RSU RAID 1 for mirrored storage on UCP4131.
Match each deployment scale to the right UCP chassis.
Start with physical scale, service-slot capacity, switching, power redundancy, and storage protection, then define the board mix for the final UCP system.
UCP1202
Desktop chassis for compact access sites that need one control board, one service board, and two built-in Gigabit Ethernet ports without rack infrastructure.
- Compact edge chassis
- 1 control / 1 service slot
- 2 built-in Gigabit Ethernet ports
UCP1600
1U rackmount chassis for branch communication systems that require multiple service boards, CSU switching expansion, and optional SEU storage in limited rack space.
- Branch rack platform
- 4 service-board slots
- CSU switching + SEU storage
UCP2120
2U chassis for enterprise access aggregation with nine service-board slots, dual-control architecture, and capacity for richer interface-board combinations.
- Enterprise expansion chassis
- 9 service-board slots
- Dual-control architecture
UCP4131
4U high-reliability chassis for core systems that require redundant AC power, dual-control architecture, SEU storage expansion, and UCP4131-only RSU RAID 1 protection.
- High-reliability core chassis
- Redundant AC power
- SEU storage with RSU RAID 1
UCP capabilities for modular communication systems.
UCP turns one hardware platform into an IPPBX core, PSTN/SIP bridge, wireless backup node, dispatch access gateway, or high-reliability communication system by selecting the right boards.
FXS/FXOAnalog access
AIU Analog Interface
Connect analog phones, fax machines, PSTN lines, or other FXS/FXO endpoints through the UCP chassis.
- Use AIU boards when the site needs analog phones, fax machines, PSTN lines, or mixed FXS/FXO access.
- AIU is the most familiar way to explain UCP to customers migrating analog endpoints into an IP communication system.
Proof chips
- AIU-8 / AIU-16
- FXS / FXO endpoints
4G/LTEWireless channels
WTU Wireless Trunk
Add GSM, WCDMA, LTE, or 4G wireless channels for mobile access, backup call paths, and wireless trunk integration.
- Use WTU boards to add cellular channels for mobile trunking, backup call routes, or locations without stable wired access.
- Wireless access can be combined with analog or digital trunks when the chassis has enough service-board slots.
Proof chips
- GSM / WCDMA / LTE / 4G
- Mobile backup paths
E1/T1/J1Digital trunk
DTU Digital Trunk
Bring E1, T1, or J1 digital trunk access into the same modular communication platform.
- Use DTU boards when the project still depends on E1, T1, or J1 trunks.
- This keeps digital public-network access inside the same modular UCP platform.
Proof chips
- E1 / T1 / J1
- PSTN trunk integration
RadioDispatch paths
RIU Radio Interface
Connect radio systems and dispatch environments when voice communication must bridge telephony and radio workflows.
- Use RIU boards to bridge radio systems with dispatch or telephone workflows.
- RIU belongs in command-room, industrial, and specialized communication scenarios where radio paths remain part of daily operations.
Proof chips
- Radio cluster paths
- Dispatch integration
MIUMagneto access
MIU Magneto Interface
Support magneto interface requirements for specialized legacy field communication and industrial voice access.
- Use MIU boards for magneto interface requirements in specialized legacy field communication.
- MIU serves targeted compatibility requirements rather than general-purpose access deployments.
Proof chips
- Magneto interface
- Legacy field voice
AudioInput / output
ACU Audio Control
Provide audio input and output paths for public-address systems, meeting rooms, and dedicated communication rooms.
- Use ACU boards when external audio input or output must connect to the communication system.
- Typical scenarios include public-address links, meeting rooms, control rooms, and dedicated communication spaces.
Proof chips
- Audio input / output
- Public-address access
RAID 1UCP4131 storage
RSU RAID Storage
Provide RAID 1 storage protection for UCP4131 deployments that require mirrored storage together with the supported SEU configuration.
- Use RSU only when a UCP4131 project requires RAID 1 storage protection.
- RSU applies to UCP4131 projects that pair RAID 1 protection with the supported SEU configuration.
Proof chips
- RAID 1
- UCP4131 only
SATAStorage expansion
SEU Storage Expansion
Add SATA storage expansion on supported rackmount chassis for recordings, logs, or local storage requirements.
- Use SEU to add SATA storage on supported rackmount UCP chassis.
- Storage expansion is relevant for recording, logs, or local data needs after the access board mix is clear.
Proof chips
- SATA storage
- Rackmount chassis option
