GENERAL 1.1 Document Purpose This document provides general, installation and testing information for the 12-channel and 6-Channel 2/4-Wire E&M/Transmission Only (TO) Channel Units. This document covers model numbers 3652-80 and 3652-81. 1.2 Document Status This document is reprinted to add E&M circuit diagrams. 1.3 Equipment Function The 2/4-wire E&M/TO unit is part of the 360-80 Intelligent Channel Bank (ICB). 1.4 Equipment Location/Mounting The 3652-80 plugs into any full size slot of the Charles Industries 360-80 ICB. The 3652-81 plugs in to the half- size slot of the ICB. This unit can only be used in issue 3 or later ICB shelves. 1.5 Equipment Features This unit provides the following features: � Supports 2/4-wire E&M and TO operation � Supports E&M signaling types (I, II, III, IV or V) � Supports E&M tandem operation with signaling type V � Provides E&M type DC signaling that is separate from the voice leads � Supports bidirectional per channel loopback � Supports both 2-wire and 4-wire interfaces for either 600 or 900 ohm operation � Supports non-signaling transmission only (TO) operation using full 8-bit encoding/decoding � Accommodates transmit and receive TLP levels from −19 to +13 dBm (extended range) in 4 wire mode � Prescription attenuation control of up to 32 dB in 0.1 dB increments in both the transmit and receive paths � Provides Mu-law encoding for T1 and A-law encoding for E1 � Temperature hardened (−40 to +65 C) � UL/CSA approved and FCC verified. 1.6 Indicators This unit is able to provide a variety of status information. The following is a list of status information available through the management interface: � Per channel forced busy (yes, no) � Per channel Busy LED state (On, Off) � Per channel time slot used (T1=1−24, none) (E1=1−15, 17−31, none) � Per channel unit configuration (2-wire, 4-wire) � Per channel interface impedance (600, 900) � Per channel unit mode (E&M, TO) � Per channel signaling mode (I, II, III, IV, V) 2 Section 365-280-202 � Per channel transmit level setting (−19 to +13 dBm in 0.1 dB increments in 4-wire mode and −19 to +7 dBm in 0.1 dB increments in 2-wire mode) � Per channel receive level setting (−19 to +13 dBm in 0.1 dB increments in 4-wire mode and −19 to +7 dBm in 0.1 dB increments in 2-wire mode) � Per channel loopback (loopback, release) � Per channel CGAI action (Idle, Busy) � Per channel CGAD action (Idle, Busy). 1.7 Control Interface This unit is managed through the craft port or the Network Management Software (NMS), which controls the pro- visioning of the unit and obtains status information from the unit. Provisioning is described in the Optioning sec- tion of this document. For operation, see the craft port or NMS documentation. This unit will maintain its default provisioning until that provisioning is altered through the control interface. If this unit’s provisioning is changed, it will maintain the new provisioning even if power is lost. If replaced with a new unit, the new unit will default to the same provisioning as was set for the prior unit. If this unit is installed in a loca- tion that was used by a different type of unit, this unit will use its own default provisioning. 2. INSPECTION 2.1 Inspect for Damages Inspect the equipment thoroughly upon delivery. If the equipment has been damaged in transit, immediately re- port the extent of damage to the transportation company. 2.2 Equipment Identification Charles Industries’ equipment is identified by a model and issue number imprinted on the front panel or located elsewhere on the equipment. Each time a major engineering design change is made on the equipment, the issue number is advanced by 1 and imprinted on subsequent units manufactured. Therefore, be sure to include both the model number and its issue number when making inquiries about the equipment. 2.3 Static Concerns Each unit is shipped in static-protective packaging to prevent damages from electrostatic charges. Use approved static-preventive measures, such as static-conductive wrist straps and a static-dissipative mat, when handling units outside of their protective packaging. A unit intended for future use should be tested as soon as possible and returned to its original protective packaging for storage. STATIC-SENSITIVE This equipment contains static-sensitive electronic devices. To prevent electrostatic charges from damaging static-sensitive units: � Use approved static-preventive measures (such as static-conductive wrist straps and static-dissipa- tive mats) at all times whenever touching units outside of their original, shipped, protective packaging. � Do not ship or store units near strong electrostatic, electromagnetic, or magnetic fields. � Always use the original static-protective packaging for shipping or storage. Return a tested unit to its original protective packaging for storage. 3 Section 365-280-202 3. APPLICATION GUIDELINES 3.1 E&M Channel Units These channel units provide E&M type DC signaling. Both 2W and 4W modes are available. E&M units are typi- cally used to provide PBX tie trunk channels, but are widely used for other services and applications that require a separate signaling path. See Figure 3. Toll 360−80 360−80 XMT RCV Toll Trunk Trunk or RCV XMT or T1/E1 Facility PBX PBX 2W or 4W 2W or 4W E Trunk E Trunk E&M E&M M M Figure 3. Typical PBX Tie Trunk Application Using E&M Channel Units The units can also be used in a tandem configuration if only two-state signaling is needed (see Figure 4). Signal- ing type V would be selected for both units in this application. 360−80 360−80 XMT RCV T1/E1 Facility T1/E1 Facility RCV XMT 2W or 4W 2W or 4W M E&M E&M E M E Figure 4.

CIRCUIT DESCRIPTION The following describes one of the circuits on the unit and can be considered typical of any of the circuits. 4.1 Incoming Voice Operation (From the Network) Each circuit, or channel, of the unit receives digital voice and signaling information from the ICB’s network inter- face unit. The digital voice information is converted to analog voice information and conveyed to the receive level adjusting circuit. Receive Transmission Level Point (RTLP) is the level of the analog signal that is output when a 0bBm signal is received from the digital network. If the RTLP is set to +6.0 dB, then a 0dBm0 signal received from the network will be output as a +6.0 analog signal. The signal then goes through a hybrid, which transmits the voice information to the two wire transmission facilities. The impedance of the hybrid can be configured for either a balanced 600 or 900 ohm facility. In the 4W mode, the voice information does not use the hybrid; it goes directly to the line transformer, which can be configured for either a balanced 600 or 900 ohm facility. 4.2 Outgoing Voice Operation (To the Network) In the 2W mode, analog voice information presented from the 2W transmission facility is passed to the 600 or 900 ohm impedance matching hybrid and is then conveyed to the level adjusting circuit. In the 4W mode, the analog voice information is presented from the 4W facility to the line transformer that can match either a 600 or a 900 ohm facility. The voice information is then conveyed to the level adjusting circuit. Transmit Transmission Level Point (TTLP) is the level of analog signal that is transmitted toward the digital network or 0dBm0. Therefore, if the TTLP is set to −16.0 dBm, then a −16.0 dBm0 analog signal will be transmitted onto the network as 0dBm0. From the level adjusting circuit, the analog voice information is converted to digital and multiplexed with the other chan- nels and sent to the network interface unit to be transmitted to the far end equipment. 4.3 Incoming E&M Signaling Operation The digital signaling information from the network interface unit is converted into the A and B signaling highway information. Although both the A and B signaling highways are supposed to be the same, in the event they are not, only the A highway is observed. The incoming A signaling highway is used to illuminate the busy LED and operate the relay to change the signaling leads on the analog output of the unit. The unit is compatible with E&M modes type I through V (see figure 6). When the incoming A signaling highway changes states from idle (0) to busy (1), the relay is operated and the output E, or E and SG lead, change states from idle to busy. 4.4 Outgoing E&M Signaling Operation When the M, or M and SB leads to the unit are changed from their idle to busy conditions, the unit will change the outgoing A&B signaling highways’ states from idle (0) to busy (1). Type I and V E&M signaling only require the use of the E and M leads. Type II, III, and IV require the use of both the E&M and SG and SB leads on the unit (see figure 6). For types I and V, it is also essential that the power re- turn ground connected to the ICB be the same reference as the power return ground used by the interfacing local E&M equipment. The transmission and signaling leads are designed to be used only in local, in-house wiring facil- ities and not to outside plant wiring facilities. In transmission only (TO) applications, only the transmissions lead, T&R or T&R and T1R1, are used. The unit, when configured for TO, is configured for full 8 bit encoding and decoding. There is no signaling with transmis- sion-only. To allow tandem operation, use E&M signaling type 5. Connect the E-lead of the ICB to the M-lead of a second E&M card, and the E-lead of the second E&M card to the M-lead of the ICB. 5 Section 365-280-202 4.5 CGAI/CGAD Operation Each circuit can be configured for a different operation in a Carrier Group Alarm. It is important the E and EB leads are wired correctly to prevent incorrect signaling if a channel bank power failure occurs. When a T1 Carrier Group Alarm is detected, CGAI will immediately initiate the signaling condition defined for the circuit under the CGAI signaling state. This signaling condition will be present for 2.5 seconds. At 2.5 seconds, the Carrier Group Alarm Delayed signaling condition will become active and the signaling state under CGAD re- mains active until the T1 Carrier Group Alarm is removed.

It is important that the E & EB polarity be maintained when connecting with far end equipment. For signaling types I & V to function correctly, it is important to connect the battery return to earth ground. Figure 7. E&M Signaling Circuit Diagrams 6 Section 365-280-202 5. INSTALLATION 5.1 Installing the Unit 5.1.1. Attaching the Rear Panel The rear panel of the full size unit (3652-80) should be installed before all the units are installed in the shelf, and before wiring begins. The half size unit (3652-81) does not require a new rear panel. + T&R and T1&R1 + Figure 8. 3652-80 2W/4W E&M/TO Rear Panel 5.1.2. Installing a New Unit Make sure that all manual optioning is done on the new unit. See Figure 9 and Figure 10 for option locations. Note: Any manual optioning that is not done before the card is installed will require the system to discontinue service on all circuits when the card is removed for optioning in the future. Step Action 1. Set hardware options as described in the Optioning section of this document. 2. If not already installed, install the rear panel, screwing it to the appropriate mounting locations on the shelf using the provided hardware. WARNING If there is already a rear panel installed on the shelf, check for interference when mounting. The rear panel may need to be removed and replaced with the rear panel that has been shipped with the new unit. 3. Align the unit with the card guides and slide it all the way into the shelf. 4. Once the unit is fully inserted, tighten the securing screw on the front panel of the unit. 5. Wire the unit according to the wiring instructions provided in this document. 6. Once the unit has been inserted properly, a self-test is performed to ensure that it is compatible with the network management software on the system. After the self-test is performed, check the software pro- visioning of the card using either the front panel craft interface on the front of the controller unit or the network management interface on the rear of the controller (see the Network Management section for more information on the operation of this interface). 5.1.3. Installing a Replacement Unit If you are replacing a unit that is already in service, make sure the unit is the same type and that the hardware has been optioned the same as the previous unit. Step Action 1. Remove the wiring connectors from the front and rear of the unit. 2. Unscrew the front panel securing screw to release the unit from the shelf. 3. Using the card ejector, remove the unit from the shelf. 4. Before installing the new unit, make sure the optioning is the same as the unit removed. 5. Follow the procedure for installing a new unit. 7 Section 365-280-202 5.2 Wiring the Unit The pin chart for the full size (3652-80) appears in Table 1.
