Product Description
With the ongoing deployment of IP networks, the efficiency and cost-savings gains of IP are being realized for a variety of applications and functions. Largely left out of this evolution have been the circuit-based applications such as time- division multiplexing (TDM) leased line and voice private branch exchange (PBX) connections, serial encryption connections, and analog and digital radio systems networking, because their synchronous transport requirements are not addressed by a packet-based network. The Juniper Networks® CTP Series Circuit to Packet Platforms enable customers to connect these circuit-based applications easily and reliably across the IP network, bringing them the advantages of converged multiservice IP networking.
The CTP Series includes the Juniper Networks CTP151, CTP2008, CTP2024, CTP2056 Circuit to Packet Platforms, and the Juniper Networks CTPView Network Management System. The products are designed for government agencies, enterprises and service providers running circuit-based applications and range in size, port capacity and redundancy options.

Primary Circuit to Packet Solutions
| Application | Application Description | Benefit |
| SS7 transport over IP | Provides transport of dedicated T1 or E1 SS7 links over the IP/ MPLS network. | Eliminates point-to-point T1 and E1 links required for transporting SS7 traffic and allows convergence over the IP/MPLS network. |
| TDM over IP solution | The provisioning of point-to-point TDM trunks over the IP network does not require changes to the TDM equipment. | Allows the continued use and investment protection of the existing TDM equipment or an easy transition path from a TDM network to an IP network. |
| PBX interconnect over IP solution | Provides E1 and T1 trunking for PBX interconnection over the IP network. | Reduce WAN infrastructure cost through the elimination of costly point-to-point circuits and leased lines required to support TDM and/or ATM networks. Circuit emulation over IP enables seamless transition to IP transport without upgrading your entire infrastructure to VoIP. |
| PBX Extension over IP with 2WFXS/2WFXO | Provides two-wire analog PBX to phone extensions over IP and two-wire PBX to PBX/central office connections over IP. Private- line automatic ringdown (PLAR) is also supported. | Reduces IT expenditures by enabling PBX tie lines to be transported across less expensive IP data network connections. Analog voice traffic is converted to IP, eliminating the need for costly T1 tie lines. |
| Leased line extension over IP solution | Supports standards-based encapsulation and DS0 bundling. IETF PWE3 RFCs, SAToP and CESoPSN are supported. | Enables full, fractional and DS0 bundling and mapping of T1 and E1 service provisioned over an IP/MPLS network and enables interoperability between vendors. |
| Radio over IP solution | Allows for connectivity of analog and digital radios over IP networks. | Provides a mechanism to deploy these systems over IP networks while maintaining critical communications. |
| Serial encryption over IP solution | Provides transport of KG/KIV bit-synchronous cipher text across an IP network. | Eliminates the need to deploy TDM or ATM equipment—saving cost, time, space, and power. |
| T1 and E1 backup over IP | Point-to-point T1 or E1 circuits can be automatically backed up over the IP/MPLS network. | Eliminates redundant point-to-point circuit costs. The end application does not need to detect IP, saving software and hardware upgrade costs. |
Features and Benefits
Key features and benefits of the CTP Series Circuit to Packet Platforms include the following.
| Feature | Feature Description | Benefit |
| Software circuit provisioning | EIA530, RS-232, V.35, 4WTO, T1, and E1 circuit types are software configured including the line encoding, clocking, rates, and IP settings. | The network quickly fulfills new and changing end user requirements without deploying excess hardware. |
| Scalable product family | A family of four CTP Series Circuit to Packet Platforms provides different port densities. Products can address the requirements of small remote sites through large central network hubs. | Network designers control costs by selecting the CTP Series Circuit to Packet Platforms most suitable for the site when considering circuit quantities and anticipated growth. |
| CTPView Network Management System | Secure, multi-user, web-based network management system provides network monitoring, circuit provisioning, IP performance reporting, database backup, and circuit troubleshooting tools. | Managers quickly deploy circuits and services while proactively monitoring the network. IP performance reports provide detailed information on IP network jitter, delay and packet loss. Circuit troubleshooting tools include integral BERTS and loops to facilitate quick trouble resolution. |
| Multiple system and circuit clocking solutions | CTP Series Circuit to Packet Platforms are designed to use multiple external clocks as monitored and prioritized system references. Circuits are configured to use the system clock, external circuit timing, or to adaptively recover clock information from the remote port when required by the application or when no reference is configured. |
Circuit reliability is improved since ports and systems are configured with the clocking solution that is most appropriate for the particular application. |
| Auto switch | The status of the CTP Series circuit ports is monitored, and the circuit is automatically switched to an alternate local or remote port when a failure is detected. | Network and circuit reliability are increased when the circuits are automatically restored to alternate locations and equipment in the event of an equipment, site or network failure. |
| Packet protector | Redundant packets are created and transmitted to the IP network and then processed by the receiving CTP Series. | Circuit quality and reliability are increased when IP connections experience significant packet loss caused by bit errors. |
| Autobaud | The input timing leads are monitored, and the circuit rate is automatically changed at both ends of the network if a rate change is detected. | Flexible rate agility enables immediate and automatic provisioning changes. |
| Loops and BERTs | Each CTP Series port supports interface and network loops and the ability to generate and monitor a bit error rate test with up to nine BERT patterns selectable. | Support for standard circuit troubleshooting tools that are built into the CTP Series help to quickly isolate network, circuit or cable problems. |
| Layer 2 Serial-to-Ethernet IP aggregation | The CTP Series Circuit to Packet Platforms can aggregate layer 2 traffic from serial interfaces onto a Fast Ethernet or Gigabit Ethernet interface. Layer 2 protocols supported are Frame Relay, PPP and Cisco-HDLC. Each CTP Series port is connected to a different VLAN. | The ability to aggregate layer 2 traffic on the CTP Series from multiple serial interfaces reduces the router interfaces needed for low-speed IP aggregation. |
| Port mirroring | The CTP Series is able to port-mirror any transmit or any receive up to 10 local or remote destinations. | Port mirroring minimizes the bandwidth required to send the same traffic to multiple sites across the network. It enables easy monitoring for troubleshooting circuit problems. Port mirroring enables the replication of data to multiple local or geographically dispersed locations. |
| Analog voice—4WE&M | The CTP Series supports analog 4WE&M type I, II,and V interfaces with software selectable transmit and receive-level adjustments per interface. | The ability to support analog 4WE&M interfaces allows the CTP Series Circuit to Packet Platforms to offer another PBX trunking option. The 4WE&M interface can also be used for radio interfaces with push-to-talk requirements. |
| Analog voice—2WFXS | The CTP Series supports analog 2WFXS loop start, ground start, and PLAR modes with software selectable transmit and receive-level adjustments per interface. | The ability to support analog 2WFXS interfaces allows the CTP Series Circuit to Packet Platforms to offer 2-wire voice extensions over IP for remote phones, remote central office or PBX equipment. |
| Analog voice—2WFXO | The CTP Series support analog 2WFXO loop start and ground start modes with software selectable transmit and receive-level adjustments per interface. | The ability to support analog 2WFXO interfaces allows the CTP Series Circuit to Packet Platforms to offer 2-wire voice extensions over IP to remote phones, or remote central office or PBX equipment. |
| IRIG-B | The CTP Series supports an inter-range instrumentation group time code (IRIG-B) signal to be transported through an IP network. IRIG-B encodes day of year, hour, minute, and second data on a 1-KHz carrier frequency, with an update rate of once per second. | Provides the ability to support IRIG-B transport over the IP network with options to configure direction, output high and low levels, and data range per interface. |
