TN2185B  ISDN-BRI, 4-Wire S/T-TE Interface 
(can be used as an alternative to TN464F or 
TN2464)
The TN2185B supports eight 4-wire ISDN BRI line S interfaces, each operating at 192 
Kbps, with 2 B-channels (64 Kbps) and 1 D-channel (16 Kbps). The TN2185B interfaces 
to the DEFINITY LAN bus and the TDM bus to provide the TE side of the BRI interface.
The TN2185B is similar to the TN2198 except the TN2185B is a 4-wire S interface 
instead of a 2-wire U interface. Another difference is the function of the SCOTCH/NPE 
and SAKI are replaced by the network control element (NCE). 
For each port, information communicates over two 64 Kbps bearer channels called B1 
and B2, and over a 16 Kbps channel called the demand channel, or D channel. The D 
channel is used for signaling. Channels B1 and B2 can be circuit switched 
simultaneously, or either of them may be packet switched, but not both at once. The D 
channel is always packet switched. The circuit switched connections have a µ-Law or 
A-Law option (on a per-board basis) for voice operation and operate as 64 kbps clear 
channels when in the data mode. The packet switched channels support the LAPD 
protocol, however, the TN2185B does not terminate on LAPD protocol. The S interface 
does not support switching of both B channels together as a 128 Kb/s wideband channel. 
The TN2185B has a long range up to 18,000 feet (5486 m) maximum from the system to 
the NT1 device. In a multiple terminal environment, the B channels are shared only on a 
per-call basis. For example, if the B2 channel is for data, then the B2 by 1 terminal 
excludes the others from having access to it. When a used device communicates over 
the D channel to access B1 or B2, that channel is owned until the call is taken down (no 
party on line). The D channel is always shared among the terminals. Replaces the 
TN-PRI/BRI PRI to BRI converter (ETSI-BRI) and can be used as an alternative to the 
TN464F or the TN2464.
The ability of outpulse in-band DTMF signals or end-to end signaling is supported by the 
TN2185B. 
QSIG Call Completion is supported, however, QSIG Supplementary Services are not. 
ISDN-BRI trunks can be used as inter-PBX tie lines using the QSIG peer protocol.

TN2198  ISDN-BRI, 2-Wire U Interface 
The TN2198 allows connection to the ANSI standard 2-wire U-Interface. The 2-wire 
interface from the TN2198 connects to an NT1 network interface. The 4-wire interface on 
the other side of the NT1 may connect to 1 or 2 telephones. The TN2198 does not 
provide a trunk-side interface as does the TN2185 circuit pack.
The TN2198 contains 12 ports that interface at the ISDN U reference point. For each port, 
information communicates over two 64 Kbps bearer channels called B1 and B2, and over 
a 16 Kbps channel called the demand channel, or D channel. The D channel is used for 
signaling. Channels B1 and B2 can be circuit switched simultaneously. The D channel is 
always packet switched. The TN2198 requires a packet control circuit pack (TN778) on 
Category B ONLY. Each port supports 1 voice terminal, such as 500 (rotary dial) and 
2500 terminals (DTMF dial).
The D channel supports the LAPD protocol and is consistent with the CCITT Q.920 
Recommendations for D channel signaling. 
In a multiple terminal environment, the B channels are shared only on a per-call basis. 
For example, if the B2 channel is used for data, then the use of B2 by 1 terminal excludes 
the others from having access to it. When a device communicates over the D channel to 
access B1 or B2, that channel is owned until the call is taken (no party on line). The D 
channel is always shared among the terminals. The TN2198 interfaces with the TDM bus 
and packet bus in the DEFINITY backplane and terminates with 12 ISDN basic access 
ports.
The TN2198 has a long range to 18,000 feet (5486 m) maximum from the system to the 
NT1 device and uses standard protocol ANSI T1.601. The TN2198 has a 160 Kbps line 
rate, consisting of 2 bearer channels at 64 Kbps channels each, the D channel at 16 
Kbps, framing at 12 Kbps, and maintenance at 4 Kbps. The circuit pack uses demand 
channel (ringing, tone, and so forth), 16 Kbps channel, and supports up to 24 telephones 
or data modules per circuit pack.
The TN2198 is not offered as a BRI Tie Trunk.
TN2199  Central Office Trunk for Russia
The TN2199 is a 4-port, 3-wire, loop-start trunk circuit pack that can be used as a DID 
trunk, CO trunk (2-way, 1-way incoming, or 1-way outgoing CO). The TN2199 combines 
the functionality of the DID trunk and the 1-way outgoing CO trunk (DIOD trunk). This 
circuit pack is used with the call classifier circuit pack (TN744D or later) or the 
Tone-Clock/ tone detector (TN2182B or later) to accomplish MF shuttle signaling (similar 
to R2-MFC signaling). Supports incoming ANI.

TN2202  Ring Generator for France
The TN2202 ring generator circuit pack supplies 50 Hz ringing power. The TN2202 
supplies balanced ringing, by a modified backplane, to terminals connecting to the 
TN2183 multi-country analog line circuit pack when administered for France analog 
transmission.
The TN2202 plugs into the power unit slot and is required for each carrier containing 
analog lines (1 in an single-carrier cabinet or 1 in each port carrier of a MCC). A 1-lead 
modification is required in each backplane using TN2202. This is true for all products 
made for France. The TN2202 produces 2 symmetrical voltages (typically 28V rms) with 
respect to ground, and takes –48 VDC, –5 VDC, and ground from the backplane and 
generates 2 x 28V rms with added –48 VDC.
TN2207  DS1 Interface, T1 (24-Channel)
and E1 (32-Channel), for MMCH
The TN2207 circuit packs support digital signal level 1 (DS1) rate (24 channel) and E1 
rate (32 channel) digital facility connectivity. All TN2207 suffixes support CO, Tie, DID, 
and off premises station (OPS) port types using the robbed-bit signaling protocol, the 
proprietary Bit-Oriented Signaling (BOS) 24th channel signaling protocol, and the 
DMI-BOS 24th channel signaling protocol. The circuit packs also support ISDN-PRI 
connectivity T1 or E1. 
In DS1 (24 channel) mode, a DS1 interface is provided to the DS1 facility. The TN2207 
circuit packs provide board-level administrable A-Law and µ-Law companding, CRC-4 
generation and checking (E1 only), and Stratum 3 clock capability. 
The TN2207 provides test jack access to the DS1 or E1 line and support the 120A 
integrated channel service unit (CSU).
All suffixes have line out (LO) and line in (LI) signal leads. The Line Out and Line In leads 
are unpolarized balanced pairs.
The TN2207 has additional hardware to support direct cabling to a TN787 MMI circuit 
pack.

devices. In the CallVisor ASAI/DEFINITY LAN Gateway R1 (Circuit-Pack Assembly) 
(being replaced by J58890MA-1), the TN2208 operates with the TN2170 Alarm with 
Ethernet Interface circuit pack to monitor system power and environmental status, -48 
VDC to +12 VDC power conversion for the disk drive and tape drive, and remote terminal 
access.
TN2209  Tie Trunk for Russia
The TN2209 has 4 ports used for Type 1 or Type 5 four-wire E & M lead signaling tie 
trunks, that can be automatic, immediate-start, wink-start, and delay-dial. The TN2209 
provides an interface between these four frequency signaling tie trunk lines and the 
DEFINITY TDM network. Based on a TN760D each port has modified E, and M signal 
leads for universal hardware compatibility. The TN2209 provides release link trunks 
required for the CAS feature and has administrable A-Law and µ-Law companding.
TN2210  Tone Generator
The TN2210 tone generator provides a 1780 Hz tone for an auxiliary trunk port on a 
TN763 or SN231. The external alarm interface provides a contact closure to connect to 
the TN492C remote interface circuit of the DEFINITY common control carrier. The tone is 
used by the AUTOPLEX system to support CO call associated continuity testing of trunk 
circuits between the CO and AUTOPLEX system. The circuit will provide an active alarm 
LED to indicate the circuit pack is in a fault condition.
TN2211 Optical Drive for r only
The TN2211 Optical Drive has replaced the TN1656 Tape Drive in DEFINITY ECS R8r. 
The drive provides removable storage for software upgrades, translation backups, 
announcement file backups, core dumps, etc., as did the TN1656 Tape Drive. The Optical 
Drive has several advantages over the TN1656 Tape Drive. 
nwriting to the optical disk is considerably shorter than writing to tape. A full backup 
will take approximately 20 minutes, whereas the Tape Drive takes up to 95 
minutes. 
nthe optical disk is more reliable because it does not error due to:
nblock allocation (has several spare block available
nnumber of accesses to the media
