Handling Energized Products General Safety Practices Do not touch or tamper with the power supply when the power cord is connected. Line voltages may be present inside certain products even when the power switch (if installed) is in the OFF position or a fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous, energy hazards may still exist.
PAGE 7
The maximum permissible current capability of the branch distribution circuit that supplies power to the product is 16A (20A for USA and Canada). The circuit breaker in the building installation should have high breaking capacity and must operate at short-circuit current exceeding 35A (40A for USA and Canada). Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate the circuit breaker of the panel board that services the equipment and switch it to the OFF position.
PAGE 8
When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The grounding and bonding of the ground connections should comply with the local codes. The telecommunication wiring in the building may be damaged or present a fire hazard in case of contact between exposed external wires and the AC power lines. In order to reduce the risk, there are restrictions on the diameter of wires in the telecom cables, between the equipment and the mating connectors.

Diagnostics The detection and isolation of a malfunction or mistake in a communications device, network or system. Encapsulation Encapsulating data is a technique used by layered protocols in which a low level protocol accepts a message from a higher level protocol, then places it in the data portion of the lower-level frame. The logistics of encapsulation require that packets traveling over a physical network contain a sequence of headers.
PAGE 13
IP Address Also known as an Internet address. A unique string of numbers that identifies a computer or device on a TCP/IP network. The format of an IP address is a 32-bit numeric address written as four numbers from 0 to 255, separated by periods (for example, 1.0.255.123). Jitter The deviation of a transmission signal in time or phase. It can introduce errors and loss of synchronization in high speed synchronous communications.

Chapter 1 Introduction 1.1 Overview IPmux-24 offers a pseudowire (PW) solution for extending traditional E1/T1 services transparently over packet switched networks (PSNs) such as Ethernet, MPLS and IP networks. The device converts the data stream coming from its TDM ports into configurable-sized packets that are encapsulated using one of the PW methods (TDMoIP, CESoPSN, SAToP, HDLCoPSN) and forwarded over Ethernet, MPLS and IP networks.
PAGE 28
Chapter 1 Introduction Installation and Operation Manual Applications Figure 1-1 illustrates an IPmux-24 application in which it provides a 2G/3G cellular backhaul over an Ethernet ring. Figure 1-1. 2G/3G Cellular Backhaul over an Ethernet Ring Features E1 Interface The E1 interfaces comply with G.703, G.704, and G.823 standards. They support unframed, framed with or without CAS/CCS. The E1 interfaces can be monitored for alarms and error statistics. T1 Interface The T1 interfaces comply with ANSI T1.
PAGE 29
Installation and Operation Manual Chapter 1 Introduction Timing IPmux-24 maintains synchronization between TDM devices by deploying advanced clock recovery mechanisms. Available timing modes are: • • • • Loopback (Rx clock) Adaptive Internal clock External clock. System clock ensures single clock source for all TDM links. The system clock uses master and fallback timing sources for clock redundancy. IPmux-24 provides system clock output via external clock connector.
PAGE 30
Chapter 1 Introduction Installation and Operation Manual MPLS IPmux-24 encapsulates PW payload with MPLS labels for transporting it over MPLS networks (TDMoMPLS, CESoMPLS, SATOPoMPLS, HDLCoMPLS). Saving up to 20 bytes of overhead in comparison to the standard PWoIP encapsulation, TDMoMPLS is ideal for bandwidth-sensitive networks. IP The data stream coming from the E1 or T1 port is converted into IP packets that are transported over the Gigabit or Fast Ethernet ports, and vice versa.
PAGE 31
Installation and Operation Manual Chapter 1 Introduction HDLCoPSN IPmux-24 also supports HDLCoPSN (HDLCoMPLS and HDLCoIP) transmission. This makes IPmux-24 suitable for the following data transfer applications: • Port-mode Frame Relay (FRAD) • Transparent X.25 (PAD) • Transparent PPP (router). The HDLCoPSN is implemented in IPmux-24 according to the IETF RFC 4618 (excluding clause 5.3 – PPP) and RFC 5087. The HDLC uses bit stuffing to ensure the bits stream continuity.

This option provides clear channel end-to-end service (unframed).
PAGE 35
Installation and Operation Manual Chapter 1 Introduction Testing Diagnostic capabilities include E1/T1 local and remote loopback tests for rapid localization of faults. The E1/T1 traffic can be looped locally, toward the line, or toward the remote end (see Chapter 6 for more information). Timing Modes IPmux-24 supports different timing modes to provide maximum flexibility for connecting the IPmux-24 E1, T1 ports.
PAGE 36
Chapter 1 Introduction Installation and Operation Manual External Network Timing When the edges of the network are synchronized by an external network clock source, all the IPmux-24 units should be configured to work in loopback timing mode (see Figure 1-3). This topology enables any-to-any connectivity. Figure 1-3. IPmux-24 in Loopback Timing Mode External timing from the network can also be issued to IPmux-24 by external clock input. Figure 1-4.
PAGE 37
Installation and Operation Manual Chapter 1 Introduction Adaptive Timing When a common clock is not available on all the ends of the network, one of the IPmux-24 devices is configured to work in loopback timing, while the other IPmux24 device is configured to work in adaptive timing (see Figure 1-5). Figure 1-5. IPmux-24 in Adaptive Timing Mode In leased line applications, the carrier does not know which side provides the source clock.

Installation and Operation Manual Chapter 6 Diagnostics and Troubleshooting Parameter Description Jabber The number of frames that are too long and have an invalid CRC. A jabber is transmission by a data station beyond the time interval allowed by the protocol, usually affecting the rest of the network. In an Ethernet network, devices compete for use of the line, attempting to send a signal and then retrying in the event that someone else tried at the same time.

Installation and Operation Manual Chapter 6 Diagnostics and Troubleshooting Table 6-3. Bundle Connection Statistics Parameters Parameter Description Sequence Errors The number of seconds with sequence errors since the last clear. Each packet transmitted by IPmux-24 holds a sequence number. The receiving IPmux-24 checks these numbers at the receive mechanism and expects to see that each new incoming packet is “in sequence” relative to the previous one (i.e., packet no. 5 is received after no. 4).

Chapter 6 Diagnostics and Troubleshooting Installation and Operation Manual Parameter Description Jitter Buffer Underflows The number of seconds with jitter buffer underflows since the last clear. IPmux-24 is equipped with a “Packet Delay Variation Tolerance” buffer, also called a “jitter buffer”, responsible for compensating for IP networks delay variation (IP jitter). The jitter buffer is configured in milliseconds units and exists for each bundle independently.
PAGE 159
Installation and Operation Manual Chapter 6 Diagnostics and Troubleshooting Parameter Description Jitter Buffer Overflows The number of seconds with at least one jitter buffer overflow event since the last clear. Explanation: In steady state, the jitter buffer is filled up to its middle point, which means it has the space to hold an additional similar quantity of packets. Overflow is opposite phenomenon of the Underflow, i.e.

Installation and Operation Manual Chapter 6 Diagnostics and Troubleshooting UDP Destination Port The IPmux uses the UDP protocol (Layer 4) in order to transfer the TDMoIP traffic. In the UDP protocol, the Destination port field is always set to the decimal value of 2142, hence all the packets leaving the IPmux are tagged accordingly. This unique value was assigned to RAD by the IANA organization for TDMoIP applications.
