1. Encapsulation formats supported by an EGS4 board on an OSN 3500: a. HDLC: supported b. LAPS: supported c. GFP-F: supported 2. Ethernet data frame formats supported by an EGS4 board on an OSN 3500: IEEE 802.3, Ethernet II, and IEEE 802.1 q/p

Bandwidth of an EGS4 board on an OSN 3500: 2.5 Gbit/s 1. N1EGS4 board:16 x VC-4, 48 x VC-3, or 1008 x VC-12 2. N3EGS4 or N4EGS4 board: 16 x VC-4, 48 x VC-3, or 504 x VC-12

Reset modes supported by an EGS4 board on an OSN 3500: 1. Warm reset: supported. 2. Cold reset: supported. A cold reset interrupts services.

Protection modes supported by an EGS2 board on an OSN 3500: 1. TPS: not supported 2. BPS: supported by N3EGS2 boards 3. PPS: not supported 4. DLAG: not supported 5. LAG: supports manual link aggregation and load sharing, and complies with the IEEE 802.3ad and IEEE 802.1AX standards. 6. LCAS: supported. LCAS can increase or decrease bandwidth dynamically for service protection, in compliance with the ITU-T G.7042 standard. 7. LPT: N2EGS2 boards support point-to-point LPT and N3EGS2 boards support point-to-point LPT and point-to-multipoint LPT, in compliance with the ITU-T G.7042 standard. 8. STP/RSTP: supports broadcast packet suppression and RSTP, and complies with the IEEE 802.1w standard. 9. MSTP: not supported
