The following sections are included in the publication:
The Cisco Systems FSIP with E1-G.703/G.704 port adapter is a chassismounted processor/interface card for use within a range of data communication (gateway and router) chassis supplied by Cisco Systems. The FSIP with E1-G.703/G.704 is a self-contained product that provides all of the hardware and software necessary to allow connection of Cisco Systems' chassis to digital leased line circuits (point to point) using CCITT recommendation G.703 operating protocols at speeds up to 2 Mbps. The FSIP with E1-G.703/G.704 is fully transportable between compatible host chassis. The choice of each compatible chassis has no effect on capabilities, functionality, or performance of the FSIP with E1-G.703/G.704.
The FSIP with E1-G.703/G.704 consists of the following subassemblies:
The FSIP with E1-G.703/G.704 provides capacity for the installation of up to four E1-G.703/G.704 adapter cards providing a maximum of eight serial port connections. Each port can provide connection to 2-Mb leased lines. Combined, the FSIP and E1-G.703/G.704 adapter cards provide all of the hardware necessary for supporting leased line communications.
Each port on the E1-G.703/G.704 port adapter is presented as a 15-pin, D-type connector. Each port is configured at the factory to offer either 75-ohm termination impedance for unbalanced operation or 120-ohm termination impedance for balanced operation. The E1-G.703/G.704 port adapter cable used is dependent on the impedance configuration. Further configuration is not necessary.
Each adapter cable provides a D-type connector to the applicable standard interface connector. Custom adapter cables must be ordered as follows:
The E1-G.703/G.704 port adapter is not intended to be used in a home environment, due to possible radio interference it might cause.
The E1-G.703/G.704 port adapter should not be connected to cabling that would be required by European Standard/Normative EN60950:1993 to be equipped with over-voltage protection. Only cables supplied by Cisco Systems should be used.
The E1-G.703/G.704 port adapter maintains bit integrity between the Network Port and the FSIP.
The worst-case delay through the E1-G.703/G.704 port adapter is 125 microseconds (∝S).
Except for Australia, the following port is designated Safety ExtraLow Voltage (SELV) within the scope of EN60950:1993:
The FSIP contains SELV circuitry. Ensure that attachments at the interconnection ports of the apparatus are also SELV circuits. SELV circuits are so designed and protected that, under both normal conditions and a likely fault condition, the voltage that can be drawn is not hazardous.
Always disconnect the chassis from the power supply before removing any covers.
Always disconnect the host product chassis from any analogue telephone circuits, basic access, or primary access Integrated Services Digital Network (ISDN) before removing any screws.
Failure to install the FSIP with E1-G.703/G.704 in accordance with these instructions will invalidate the approval.

This section describes special installation requirements for the following assemblies:
Where applicable, these assemblies are approved only for installation in a host and with host attachments, which are either type approved for such apparatus or covered by a General Approval. Except at the edge connector, which plugs into the host's expansion slot, clearance and creepage distances of X millimeters (mm) and Y mm, as listed in Table 1, must be maintained between the cards and other parts of the host including any other expansion cards fitted.
Creepage distance is defined as the minimum distance between two points (following the contour of the insulator) measured across the surface of an insulator. Clearance distance is defined as the minimum distance between two points (line of sight) measured in air.
Table 1 Creepage and Clearance Distances Based on Voltage
| Voltage Used or Generated by Other Parts of the Host or Expansion Card (Vrms(1) or VDC(2)) | Creepage (Y mm)(3) | Clearance (X mm) |
|---|---|---|
| Up to 50 | 2.4 (3.8) | 2.0 |
| Up to 125 | 3.0 (4.8) | 2.6 |
| Up to 250 | 5.0 (8.0) | 4.0 |
| Up to 300(4) | 6.4 (10.0) | 4.0 |
Clearance and creepage distances are measured between adjacent parts, as shown in Figure 2.
