Chapter 1 Introduction Installation and Operation Manual

1-4 Overview Egate-100 Ver. 4.0

STM-1/OC-3

Egate-100 supports two channelized STM-1/OC-3 interfaces (with APS support)

for SDH mapping (E1s over VC-12 over VC4) or SONET mapping (T1s over VT1.5

over STS1 over STS3). Either port can be configured as the active port.

SDH/SONET mode is user-configurable. Jitter output and tolerance comply with

G.825 requirements.

STM-1/OC-3 APS

The option for APS (Automatic Protection Switching) between the two

STM-1/OC-3 ports is available, and can be configured for either unidirectional or

1+1 optimized bidirectional mode, as per ITU G.841 Annex B.

Ethernet over E1/T1 Encapsulation

Egate-100 allows you to map up to 63 E1 or 84 T1 channels into the

CH-STM-1/OC-3 interface using the four protocols listed below individually or in

combination:

• GFP (G.8040) VCAT (G.7043) LCAS (G.7041): Up to 42 remote sites of

Ethernet over up to 16 E1/T1 links. Egate-100 can work opposite RAD’s

RICi-16 at the remote end to support a complete remote and central site

solution for Ethernet over n x E1/T1.

• GFP (G.8040): Up to 63/84 remote sites of Ethernet over GFP. Ethernet is

mapped over framed E1/T1. For E1, the GFP frames are mapped into

16-frame multi-frame according to G.704. For T1, they are mapped into

24-frame 1544 kbps multi-frame.

• MLPPP: Up to 42 remote sites of Ethernet over n x E1/T1, using MLPPP.

Ethernet can be mapped over up to 8 E1/T1 links. Egate-100 can work

opposite RAD’s RICi-4E1/T1 or RICi-8E1/8T1 at the remote end to support a

complete remote and central site solution for Ethernet over n x E1/T1.

• PPP/BCP: Up to 126 remote sites of Ethernet over PPP/BCP (FCD-E1 and

FCD-IP compatible). Ethernet can be mapped over unframed E1/T1, or over

fractional E1/T1: n x 64, where n (number of timeslots) = 1–31 for E1 and

1–24 for T1.

• HDLC: Up to 126 remote sites of Ethernet over RAD HDLC over E1/T1

(RICi-E1/T1, FCD-E1, and FCD-IP compatible). Ethernet can be mapped over

unframed E1/T1, or over fractional E1/T1: n x 64, where n (number of

timeslots) = 1–31 for E1 and 1–24 for T1.

Bridge

Egate-100 provides a bridging functionality between its bridge ports:

• E1/T1 over SDH/SONET (Ethernet over E1/T1 or fractional E1/T1), or T1 over

• Gigabit Ethernet ports

• Fast Ethernet management port

• Internal host.
