The MX2820 Clock Card is a plug-in card which generates a timing signal synchronized to either of two external BITS clock references. If both BITS clock references fail, the Clock Card will meet SONET Minimum Clock (SMC) holdover requirements to produce the clock reference.

Section 1, System Description - System Components NOTE The MX2820 has two power options: –48VDC or ±24 VDC. The Clock Card operates at –48VDC only. Do not deploy a ±24 VDC system if Clock Cards are deployed for STS-1 MUX timing. Clock Card Front Panel LEDs Table 1-3 provides a description of the front panel LED.

Page 53: Figure 1-7. Mx2820 Multiplexer System Configuration
The MX2820 system operates in local, loop (network), or external (BITS) timing mode. In the local timing mode, an onboard timing reference is provided. In the loop timing mode, the MUX modules synchronize with the received DS3 or STS-1 signal. Because the multiplexing/de- multiplexing process is asynchronous, each DS1 channel maintains its own Transmit and Receive timing.
Page 54: Network Interfaces
The MX2820 system multiplexes DSX-1 or E1 input signals into DS3 or STS-1 output signals. Each MUX module accepts a single DS3 or STS-1 input signal from the network side and provides 28 DSX-1 or 21 E1 outputs. For 1:1 redundant system, the MX2820 system provides two MUX modules for each DS3 or STS-1 signal.
Page 55: Environmental Alarm Inputs
For ACO, AUX1, AUX2, and AUX3A, alarms are activated when the circuit between the connecting posts is closed (a short appears across the line). For AUX3B, an alarm is activated by a cadenced input across the input posts; this input can be used to indicate a fan failure.

Page 171: Figure 5-52. Tributary Loopback Test
Select the Data Mode option to end a test in progress. Tributary A Tributary loopback loops the selected T1/E1 back to the DS3 network. The T1/E1 signal is demultiplexed through the M23 and M12/G.747 demultiplexers, looped back, and multi- plexed back up through the M12/G.747 and M23 multiplexers. During this loopback, all network receive data is passed to the DSX-1/E1 transmitters, but all data received by the DSX-1/E1 loop side is ignored and substituted with the network data.
Page 172: Figure 5-54. Digital Line/Net Loopback Test
Both loopbacks occur at the T1/E1 CODEC. Both the network and the local loop side of the loopback are executed at the edge of the CODEC, which completely tests the M13 MUX and the T1/E1 LIU.
Page 173: Remote Loopback
A Remote Loopback performs a loopback of the selected T1/E1 on the far-end M13 multi- plexer. If an M13 MUX is located at the far-end, an Analog Network loopback is executed when a Remote Loopback is engaged. This loopback is only available when the DS3 network is configured for C-bit parity framing since it requires the availability of the Far-End Alarm and Control (FEAC) channel.

All T1/E1 lines attached to the DS2 network receive data normally, but all data inserted into the T1/E1 lines attached to the selected DS2 signal are ignored and replaced by the incoming DS2 network data.
Page 178: Figure 5-60. Ds3 Loopbacks Menu
The DS3 Line Loopback test performs a loop of the DS3 signal back to the network. This loopback occurs prior to the DS3 framer and B3ZS decoder, but makes full use of the DS3 LIU in both receive and transmit directions. Therefore, any coding violations received by the DS3 LIU are inserted back into the network without modification.

Page 202: Provisioning Ip Forwarding
The IP Forwarding features of the MX2820 are compatible with those of the MX2800. From the perspective of an MX2820 system in an IP Forwarding application, the LAN is considered to have a Local side and a Remote side that are bridged together with one or more IP Forwarding channels.
Page 203: Ip Forwarding Mode
Each IP forwarding channel can be assigned one or more unique IP addresses. Each IP address that is assigned to an IP forwarding channel must be identical to an IP address of a device that resides on the Remote side of the LAN (including the SCU of the Remote MX2820 system).
